Modbus RTU to Modbus TCP Converter (LAN-Based) – Model RMC11
What challenges does this project solve:
In many industrial systems, legacy equipment still relies on the Modbus RTU protocol, while newer systems are based on Modbus TCP. This difference often complicates integration and central monitoring. The RMC11 converter was designed to bridge this gap — enabling seamless communication between old RS485-based devices and modern Ethernet-based control systems without any hardware modification. It provides a fast, reliable, and transparent data bridge between both protocols, ensuring compatibility across diverse industrial environments.
Goals (Features):
The RMC11 is a compact, rail-mounted converter designed for industrial use. It supports bidirectional conversion between Modbus RTU (RS485) and Modbus TCP (LAN), features dual LEDs for DATA, LINK, and STAT monitoring, and runs on 24V DC power.
Key capabilities include high-speed packet processing, IP addressing, and plug-and-play installation without the need for reconfiguration. Its built-in Bridge and Gateway modes allow full bidirectional communication between RTU and TCP networks. With industrial-grade isolation and robust communication filters, RMC11 ensures a secure and stable data link in noisy environments.
What challenges did I face during development:
One of the key challenges was ensuring ultra-low latency and stable conversion between Modbus RTU and TCP frames, especially in noisy industrial networks. Developing a lightweight firmware capable of maintaining synchronized, error-free communication under heavy traffic required precise timing and buffer management. Another challenge was preventing packet loss during protocol translation and guaranteeing system recovery after connection interruptions. Extensive field testing and optimization of both hardware and software ensured RMC11 could operate 24/7 with complete reliability in demanding conditions.

Modbus RTU (Hardware RS-485) to Metrics Converter – Model RMC20
What challenges does this project solve:
In industrial monitoring systems, a major issue is connecting devices that use the traditional Modbus RTU protocol to newer software platforms that typically run on network-based or open-source monitoring systems. I designed this converter to bridge that gap—so RS-485 equipment in the “Raya Technology” or “ICMAN” product lineup can connect directly to central monitoring systems or open-source software without hardware changes. The result is a stable, secure, and simple connection for collecting and displaying industrial data over the network.
What challenges did I face during development:
The main challenge was achieving full compatibility with a wide range of Modbus RTU devices, each with slight differences in frame timing and transmission. To address this, I designed the device firmware to intelligently detect and parse different structures. Maintaining network stability even when RS-485 data is noisy or incomplete required error-recovery and buffering algorithms. Aligning the internal protocol with Raya monitoring systems and converting data to a metrics format was also part of the software development and field testing. Ultimately, the product smoothly and reliably integrates virtually all legacy Modbus RTU devices with modern monitoring systems.
Goals (Features):
The primary goal was to create a smart data converter that transforms Modbus RTU data into a metrics-readable format for monitoring systems. The device connects to the network via a LAN port and automatically handles addressing and data exchange. Status indicators (DATA, LINK, STAT) are provided for quick diagnosis of faults or connection state. A 24 VDC power supply, compact DIN-rail design, and full isolation between the network and RS-485 sections are key features. The converter is designed to be compatible with any Modbus RTU device and to send data in a standard format to Raya monitoring systems as well as open-source platforms.

Zone Expander Device
What challenges does this project solve:
In large monitoring and RTU projects—especially in data racks and industrial panels—heavy wiring is a constant issue. The high number of inputs and environmental sensors (such as temperature, humidity, door, and leakage) makes cabling complex, time-consuming, and error-prone. I designed the “Zone Expander” to solve this problem—a device that modularly expands input/output zones, eliminating the need for direct wiring back to the main RTU. It improves rack order while dramatically reducing installation time and wiring errors.
What challenges did I face during development:
The main challenge was designing a module that could be compatible with various existing RTUs without introducing delay or noise in communication. To achieve this, I optimized the Modbus communication protocol so data exchange between zones happens with minimal traffic and maximum reliability. Additionally, the circuit was designed for stable operation in the noisy environment of electrical panels, ensuring error-free input state detection. Field tests showed the device reduced internal rack wiring volume by over 50% and significantly improved both the physical order and functional performance of monitoring systems.
Goals (Features):
The goal was to design a simple, reliable expansion module compatible with RAYA monitoring systems. The device connects to the RTU over Modbus and can extend multiple control zones. Key features include a compact design, easy DIN-rail installation, LED indicators for quick troubleshooting, and auto-discovery on the network. The Zone Expander lets engineers add local inputs and outputs in each rack without long cable runs, making the system structure more organized and scalable.

10-Channel Battery Health Analyzer – Model RBH10
What challenges does this project solve:
In UPS systems and data centers, knowing battery voltage alone isn’t enough to predict failure; a battery may show normal voltage while its actual capacity or internal resistance has drastically degraded. This led me to design the RBH10—an advanced version of the BM10—that, in addition to measuring voltage, also assesses true battery health. By performing controlled load tests and measuring internal resistance and the temperature of each battery, the device can determine the real condition and health percentage of every cell before failures occur, preventing unexpected outages.
What challenges did I face during development:
The biggest challenge in developing the RBH10 was combining dynamic tests (controlled load) with real-time monitoring without disrupting battery operation. Designing circuitry that could inject a precisely controlled test current for a short period while remaining fully safe required extensive testing. Accurately calculating internal resistance in the presence of electrical noise demanded precise software algorithms and signal filtering. Additionally, simultaneously collecting voltage, temperature, and resistance data from 10 separate channels—and synchronizing it with monitoring systems—posed a firmware design challenge that was solved with a multi-threaded firmware architecture. Ultimately, RBH10 became a product that analyzes not only voltage but also the physical and electrical health of batteries with high accuracy.
Goals (Features):
The purpose of the RBH10 is to build a full-fledged battery health monitor that provides more precise data than previous versions. The device includes all the capabilities of the BM10—such as simultaneous monitoring of 10 batteries and data transmission via Modbus RTU and TCP—while adding temperature sensors and load-test circuitry. With this architecture, the device can calculate internal resistance at defined intervals, track thermal behavior, and provide a Battery Health Index (BHI) for each cell. A rugged industrial design, complete isolation between inputs, and support for standard communication protocols make it an ideal choice for precise battery monitoring in data centers and critical infrastructure.

Modbus Lux Meter Sensor – Model RL5-ND
What challenges does this project solve:
With growing market demand for higher accuracy, software calibration, and remote control, the fourth version was introduced as a fundamental transformation of the LX1 series. In addition to measuring illuminance, this version can operate independently and send data over the network. With multiple light sensors, it also provides a more precise analysis of light distribution in the environment.
What challenges did I face during development:
Developing the fourth version was the most challenging stage—from managing noise resulting from multiple sensors to designing multi-protocol firmware for LAN and RS-485. Adding relays and controlling them without interfering with Modbus communication required a complete software redesign. On the mechanical side, placing three sensors in a small enclosure and ensuring accurate angle measurement was among the most complex parts of the design. The result is a more modern and fully modular product that has evolved from a simple light measurement tool into an advanced analytical and control module.
Goals (Features):
With three independent light sensors, the fourth version enables more precise measurement at different angles. The device is equipped with an OLED display, two programmable control relays, and a LAN port. In communications, support for Modbus TCP was added in addition to Modbus RTU. On the software side, internal calibration, advanced setup menus, and an improved user interface were included so the user can configure the device independently.

Modbus Earth Tester – Model RED71
What challenges does this project solve:
In electrical panels and sensitive sites, it’s not always obvious that earth is actually connected, neutral isn’t open, and phases aren’t swapped; wiring errors or loose connections can burn equipment or endanger operator safety. I designed the Earth Detector RED71 to continuously monitor the status of phase, neutral, and earth in single-phase and three-phase networks, quickly detect faults such as open neutral/phase/earth and swapping phase with neutral or earth, and report results both locally via LEDs and over Modbus RTU to monitoring systems and PLCs. Adding an RCD test button also enables periodic testing of the “residual current device” without extra equipment.
What challenges did I face during development:
The main challenge was reliably assessing earth and neutral status in the presence of heavy noise and grid harmonics; therefore, I used a differential measurement design with adaptive thresholds and EMI filtering to eliminate false detections. Electrical safety and creepage/clearance distances for three-phase operation were critical and affected component selection, routing, and isolation. Implementing the RCD test without risk or damage required precise current limiting and injection timing. On the software side, mapping faults into Modbus registers and handling transient network errors were designed so reporting is accurate while the system remains stable during momentary events. The result is a module that enhances safety and simplifies fault detection and preventive maintenance.
Goals (Features):
My goal was to build an industrial safety module that is easy to install and remains reliable in noisy environments. With isolated inputs and proper filtering, RED71 analyzes the status of all three phases (L1/L2/L3), neutral, and earth, and distinctly displays common faults such as Open Neutral, Open Hot, Open Ground, and Reverse. A Modbus RTU (RS-485) network output is provided for connection to PLC/RTU, front indicators enable fast troubleshooting, and an RCD test button (30 mA up to 2 seconds) ensures the residual current device works—right from the front panel. A modular structure and compact size make DIN-rail and rack/panel installation easy.

What challenges does this project solve:
In many industrial and infrastructure projects, precise distance measurement is needed in variable environments where ultrasonic or mechanical sensors are unsuitable due to error or range limits. I designed the RLD50-D laser distance sensor to measure distance with high accuracy in real time and send the data directly over industrial networks to monitoring systems. This device is specifically intended for production lines, smart warehouses, access control systems, and transportation projects—combining accuracy with easy network integration.
Goals (Features):
The RLD50-D sensor combines precise laser measurement with multi-protocol industrial communications. Key features include:
* Distance measurement up to 25 meters with high accuracy
* Built-in digital display for real-time readings
* Simultaneous support for Modbus TCP, Modbus RTU, and JSON over Ethernet to connect with PLCs, RTUs, DCS, or monitoring servers
* Two programmable relay outputs for threshold-based control
* Industrial housing resistant to dust with easy installation
* Parameter configuration via on-device menu and network port
This sensor is designed to connect directly to the network without additional interfaces and to send data to local or cloud monitoring systems.
What challenges did I face during development:
The main challenge was maintaining stable laser measurements under varying lighting and environmental conditions. To address this, I used optical filters and a light-intensity compensation algorithm so the device would perform accurately even in brightly lit industrial settings.
Another challenge was coordinating multiple communication protocols within a compact hardware design, which required precise software architecture and concurrent data handling over LAN and RS-485.
Mechanical design to isolate the laser sensor from environmental vibrations and shocks was also critical. Ultimately, the RLD50-D became a modern industrial sensor competitive with current standards in both measurement accuracy and networking capabilities.

Modbus PT1000 Transmitter – Model RP1000-ND
What challenges does this project solve:
In many industrial control systems and facilities, temperature data must be both viewed locally and sent over the network for central monitoring. However, most temperature transmitters either lack a user-friendly display or support only a single communication protocol. The goal in designing the PT1000 transmitter model RP1000-ND was to create a tool that can read temperature data from two sensors simultaneously with high accuracy, and share this information on the industrial network via both Modbus RTU and Modbus TCP—with a clean, simple user interface for the operator.
Goals (Features):
The RP1000-ND module is designed as a multi-protocol temperature and resistance transmitter with the following capabilities:
* Simultaneous measurement of two PT1000 / PT100 / RTD inputs with high accuracy
* Support for two industrial protocols: Modbus RTU (RS-485) and Modbus TCP (LAN)
* Large digital display for real-time viewing of each sensor’s temperature and resistance
* Menu-based UI and control keys for easy parameter configuration
* Built-in web service (Web UI) for network monitoring and configuration
* Two programmable control relays for temperature alarms or local control
* Compact design for DIN-rail installation and stable operation in industrial environments
This product, by combining local display, network communication, and a user-friendly design, bridges the gap between traditional measurement equipment and modern smart systems.
What challenges did I face during development:
One of the main challenges in designing the RP1000-ND was achieving high-accuracy measurement of RTD and PT1000 while eliminating noise on long lines. To this end, I used hardware filters and a multi-point software correction algorithm.
Another challenge was integrating both Modbus RTU and TCP into a single processor without interference in data exchange, which required a specialized firmware architecture to maintain stable responsiveness at all times.
On the user interface side, designing the graphical web service and settings menu was another challenge so the user could manage the device via a browser without auxiliary software.
Ultimately, the RP1000-ND became a modern transmitter that, in addition to high measurement accuracy, provides a better user experience for industrial operators.

Modbus Wind Speed Sensor – Model WS2-Modbus
What challenges does this project solve:
In many environmental or industrial monitoring projects, available wind speed sensors only provide a pulse output, which requires additional hardware and programming to be used with smart networks or PLCs. This leads to complexity, cost, and calculation errors. The goal in designing the WS2-Modbus wind speed sensor was to turn a simple mechanical sensor into an intelligent device based on Modbus RTU (RS-485) so it could be used directly in industrial networks without an interface module or extra software calculations in the PLC.
Goals (Features):
WS2-Modbus is an industrial wind speed sensor with high accuracy and direct network connectivity, featuring:
* Support for the industrial Modbus RTU (RS-485) protocol for stable long-distance communication
* Automatic conversion of pulse signals to a digital wind speed value (m/s)
* Adjustable calibration parameters over the network (Scaling Factor and Offset)
* Filtered digital output with low noise for reliable operation in open environments
* Rugged design for operation in harsh weather conditions
* Low power consumption and operation from 9 to 24 V
* Very small size and a two-layer design to fully integrate the electronics into the mechanical body
This device can connect directly to PLC, RTU, DCS, and SCADA systems, providing wind speed data to the controller with high accuracy and stability.
What challenges did I face during development:
The main challenge was space constraints: the mechanical sensor housing was very small, and the entire processor board, RS-485 transceiver, power supply, and noise filtering had to fit inside it. The final design used a two-tier layout to preserve dimensions while ensuring electronic stability.
Another challenge was filtering noisy pulse signals caused by strong winds or electromagnetic interference; using a digital filter and a spike-rejection algorithm produced stable, accurate final data.
Ultimately, WS2-Modbus became a smart sensor that sends wind speed data directly over Modbus RTU and can be used in weather stations, wind turbines, and industrial ventilation systems.

Networked Relay Output Module – 8-Channel – Model R08-ND
What challenges does this project solve:
The third version was a response to industry needs for direct device connectivity to industrial Ethernet networks (Modbus TCP). In this version, the module no longer had to operate solely via RS-485; it could communicate directly over LAN with central monitoring and control systems.
Goals (Features):
* Added LAN port with support for Modbus TCP
* Equipped with a digital display and settings keypad
* Added IP Filter and an internal web service for network-based configuration and monitoring
* Improved output hardware drivers for more stable performance with inductive loads
This version is essentially a combination of industrial robustness and smart networking capabilities.
What challenges did I face during development:
Integrating relay power hardware with Ethernet networking and software-based IP control was the biggest challenge. To solve this, I used a multi-board design and protective shielding so digital signals wouldn’t be affected by induced noise.
On the software side, designing the web interface and implementing network security (IP filtering) required extensive testing so the device could operate in large industrial networks without interference.
The result of these efforts was the R08-ND module, which is now one of the most complete networked relay output cards in the lineup. The third version is the final outcome of several generations of improvement—a blend of industrial design, intelligent communications, and hands-on experience from real projects.

Networked Digital Input Module – 8-Channel – Model R80-ND
What challenges does this project solve:
In the third version, my main goal was to make digital inputs accessible over LAN in addition to the serial network. This module was designed for projects that required remote monitoring or direct connectivity with cloud and industrial systems.
Goals (Features):
* 8 isolated digital inputs with high safety
* Simultaneous support for Modbus RTU and Modbus TCP
* LAN port for direct Ethernet network connection
* Digital display for viewing input statuses
* Full signal and power isolation to prevent interference
* Industrial design with dedicated outputs for micro-switches
* Stable and secure communication with PLCs, RTUs, and monitoring systems
What challenges did I face during development:
The primary challenge in the R80-ND version was implementing the Modbus TCP protocol within limited hardware resources. The high component count and the need to maintain isolation while concurrently processing serial and network data made a precise two-board design (Logic and Communication) necessary.
On the software side, coordinating the two communication ports (RTU and TCP) without interference and with zero delay consumed a significant portion of development time. Ultimately, the R80-ND became a more complete, network-centric, and reliable version that met the needs of modern industries.

Modbus Carbon Dioxide (CO₂) Sensor – Model RC2-D
What challenges does this project solve:
In the food industry, greenhouses, enclosed spaces, and workplaces, controlling CO₂ levels is critical for health, efficiency, and product quality. However, accurate CO₂ sensors are usually expensive and not connectable to industrial networks. My goal in designing the RC2-D CO₂ sensor was to build an accurate, networked, and economical device that, in addition to measuring CO₂, simultaneously measures the variables that affect it—such as temperature, humidity, and air pressure—so corrected and reliable data can be provided to control and monitoring systems.
Goals (Features):
RC2-D is a multi-parameter transmitter designed for precise air quality monitoring and carbon dioxide concentration measurement. Key features include:
* CO₂ concentration measurement with 50 ppm accuracy
* Built-in sensors for ambient temperature, humidity, and pressure
* Automatic CO₂ reading correction based on environmental conditions to increase accuracy
* Support for Modbus RTU (RS-485) for direct connection to PLC, RTU, or DCS
* High-resolution OLED display showing all four parameters simultaneously
* Two programmable relays for ventilation control or alarms
* Operation over a wide range: −10 to 60 °C and 0–95% RH
* Compact, rugged industrial design with wall or panel mounting
This device is highly practical for environmental monitoring in the food industry, greenhouses, warehouses, clean rooms, and industrial spaces.
What challenges did I face during development:
The main challenge was accurate CO₂ measurement in the presence of pressure, temperature, and humidity variations. Since each of these factors directly affects the final reading, four different sensors (CO₂, temperature, humidity, pressure) had to work together on a small, coordinated circuit.
Another challenge was simultaneous multivariable calibration. To solve this, I designed an internal correction algorithm that adjusts the final CO₂ value based on environmental data.
On the hardware side, integrating four sensors without electromagnetic interference and optimizing power management was among the most complex stages.
Ultimately, the RC2-D became an accurate, stable, and economical device compatible with industrial standards and a suitable replacement for expensive foreign models.

Modbus Temperature and Humidity Sensor – Model AK2
What challenges does this project solve:
With the expansion of smart monitoring projects, there was a need for a multi-purpose sensor with networking capabilities and software calibration. The fourth version answered this need: a device that not only sends data but also supports analysis, control, and automatic transmission of information to a server.
Goals (Features):
In AK2, in addition to the capabilities of previous versions, new features were added:
* OLED display for real-time temperature and humidity
* Two programmable control relays for automatic actions (e.g., ventilation or heating)
* LAN port with support for Modbus TCP and SNMP
* Software calibration via user menu
* New sensor cover with faster response
* Built-in logger for automatic data upload to a cloud server
This version is a complete combination of measurement, control, and networking—effectively the professional generation of the ECO series.
What challenges did I face during development:
Developing the fourth version required precise hardware–software coordination. Adding Ethernet and SNMP without increasing power consumption, as well as controlling noise between RS-485 and LAN lines, were among the key challenges. Designing the new sensor cover to achieve fast and accurate response to sudden environmental changes also involved multiple tests. Ultimately, this version became a standard for multi-functional industrial sensors.

8-Channel Input and Output Card – Model R44
What challenges does this project solve:
The second version, R44, was designed with the goal of downsizing and adding features. In the M44 version, the installation footprint was relatively large and not practical for small panels—especially greenhouses and space-constrained workshops. The aim was to design a more compact, lighter, and more powerful version that, while maintaining quality, could offer all the capabilities of the previous version.
Goals (Features)
* 4 isolated digital inputs + 4 command relay outputs
* Communication via Modbus RTU / RS-485
* Ultra-thin compact design (36 × 59 × 109 mm)
* The smallest 4-input / 4-output I/O card in the instrumentation market of Iran
* Complete hardware and software improvements over the previous version
* Suitable for small greenhouses, compact panels, and standalone controls
* Local configuration of address and software behavior
* Optimized current consumption and increased relay lifespan
What challenges did I face during development:
The main challenge in designing the R44 was fully compressing the circuits into a width of less than 3.5 cm without reducing performance or electrical safety. This required multilayer PCB design, selection of industrial SMD components, and a complete redesign of power and signal paths.
The second challenge was enhancing software capabilities such as network settings, fault management, and simplified addressing, which led to a significant increase in the R44’s intelligence compared to the previous version.
Ultimately, the R44 was introduced as the smallest 4-input / 4-output card in the markets of Iran and the world, offering a complete and cost-effective solution—especially for greenhouses and small budget automation where large systems are not economically viable.

8-Channel Input Card – Model R80
What challenges does this project solve:
After the successful experience with DIM64, market demand for smaller modules installable in tight spaces led to the design of R80. The main goal of this version was to miniaturize the design and produce the thinnest 8-channel Modbus input card in Iran—and even globally.
Goals (Features):
* 8 isolated, protected digital inputs
* Communication via Modbus RTU (RS-485)
* Ultra-thin design (36 mm width)
* LED indicators for each input and for network status
* Enhanced noise immunity with internal isolation circuitry
* Quick and easy DIN-rail mounting
* Optimized energy consumption and reduced circuit heat
What challenges did I face during development:
The biggest challenge in this version was circuit miniaturization while maintaining electrical isolation. Multilayer PCB design and the use of high-density components without interference between signal lines required a complete rerouting. On the software side, a fast and accurate data acquisition algorithm was developed so data could be transferred to the PLC in the shortest time.

RS-485 to JSON Converter – Model RMC25
What challenges does this project solve:
In many legacy industrial automation systems, data communication is only via Modbus RTU, and these systems cannot send information to web servers or cloud platforms. The goal in designing the RMC25 was to create an intelligent bridge between the legacy Modbus world and the modern internet. This converter receives data from PLCs and industrial equipment via the RS-485 port and transmits it as standard JSON over the network so servers, web applications, or cloud monitoring systems can easily consume the data.
Goals (Features)
* Converter between Modbus RTU (RS-485) and JSON / HTTP API
* Direct connection to various PLCs, RTUs, and Modbus sensors
* Ultra-compact design for installation in legacy panels
* Very small dimensions: 24 × 46 × 87 mm
* Support for network protocols to send data to a web server
* Suitable for creating a cloud gateway in existing industrial systems
* Status LEDs for connection, link, and data for real-time monitoring
* 24 VDC power supply with low power consumption
What challenges did I face during development:
The primary design challenge for the RMC25 was fitting it into a very small footprint so it could be installed in old, compact industrial panels without requiring changes to the panel’s structure. This led to a multilayer PCB design, selection of industrial SMD components, and precise engineering of power and data paths.
The next challenge was full coordination between Modbus and JSON, as the two protocols have completely different structures and require precise, flawless data conversion. Ultimately, with a dedicated middleware software design, the RMC25 succeeded in acting as a reliable bridge between traditional industrial systems and modern cloud servers.

8-Channel Relay Output Card – Model R08
What challenges does this project solve:
In the second version, my goal was to turn the RM1 card into a much more compact product with faster response so it could be used in high-density panels. I also wanted to make communication between industrial networks and servers easier so that, in addition to Modbus, data could also be sent in JSON format.
Goals (Features):
In this version, the relays were changed to industrial control relays, and the mechanical design was done so that, with a thickness of less than 3.5 cm, it became one of the thinnest relay cards in the instrumentation market in Iran and worldwide.
Modbus RTU communication was retained, but the internal software was rewritten for faster processing.
The final dimensions were reduced to 36 × 109 × 59 mm, and the hardware design became fully compact to allow easy installation in modern panels.
What challenges did I face during development:
The main challenge was integrating the power and control sections on a compact board without causing electromagnetic interference. To achieve this, I used multilayer PCB techniques.
On the software side, adding JSON support alongside Modbus required a complete redesign of the data structure. The result is a lightweight, fast, and smart module that is compatible with both PLCs and software servers.

What challenges does this project solve:
Field feedback from SP24 showed that we needed upgrades both physically and in cybersecurity. SP25 was built to fix mechanical issues, improve installation experience, and enhance communication security so that physical and software risks are reduced in sensitive environments.
What challenges did I face during development:
The main focus was increasing security without sacrificing speed; therefore, I implemented lightweight yet effective authentication mechanisms and session control. At the same time, the root causes of mechanical issues in the previous version were resolved by refining the enclosure mold and connector layout to improve durability and ease of service. The result is a more mature and secure version of the SP series.
Goals (Features):
The device’s appearance and mechanics were updated, and the physical issues of the previous version were resolved. UDP and SNMP protocols were enhanced and now provide more complete logging/monitoring. Communication security layers and authentication were strengthened compared to SP24 so access is more controlled and data exchange more resilient.

Battery Monitor – Version BM10, Model RVB102
What challenges does this project solve:
In power and UPS monitoring projects, there was a need for a system that could accurately and reliably monitor multiple batteries without the cost and complexity of large multichannel models. I designed the Battery Monitor BM-10 as an advanced version between the BM-2 and BM-20 models—a product that, while maintaining stability and ease of installation, enables simultaneous sampling of 10 batteries. With higher measurement accuracy and faster network communication, this version met the needs of data centers, telecommunications systems, and industrial power panels.
What challenges did I face during development:
During BM-10 development, one of the main challenges was maintaining stability in precise voltage measurement while increasing the number of channels. To achieve higher accuracy, signal filtering and multi-stage software calibration were added. On the other hand, optimizing the firmware to coordinate data processing and network communication without increasing latency required a complete redesign of the software architecture. Heat management and power stability were also hardware design challenges. Ultimately, the result was a product that not only surpassed previous generations in accuracy and speed but also became recognized as a stable and reliable version of the Battery Monitor series.
Goals (Features):
The goal of the BM-10 design was to combine accuracy, stability, and scalability. This model can measure the voltage of 10 batteries simultaneously and send information to the monitoring center via TCP, UDP, Modbus TCP, and SNMP protocols. The new design includes a robust ABS enclosure, industrial connectors, reinforced input isolation, and a faster processor. The internal firmware was rewritten to increase sampling accuracy, optimize data transmission rates, and fully resolve errors from previous versions. An improved web interface also provides real-time status reporting and automatic data logging.

Networked Security Panel – Model SP24
What challenges does this project solve:
With site expansion, the need for quick status visibility and diverse protocols increased. I developed SP24 to not only improve TCP stability but also support UDP and SNMP, providing more real-time feedback to the control center; as a result, troubleshooting and monitoring became much faster and more precise.
What challenges did I face during development:
Coordinating three communication paths and handling TCP/UDP/SNMP packets concurrently without increasing latency required a redesign of the network stack. On the hardware side, fitting the new components into a smaller enclosure while maintaining ventilation and EMC was a practical challenge that was solved through revised layout and shielding.
Goals (Features):
I replaced the old display with an OLED for better readability and longer lifespan. The enclosure and industrial design were revamped for easier installation and reduced rack footprint. A set of bugs from the previous version was debugged, and Link, Status, and Data LEDs were added so communication and processing states are instantly visible.

I had to write a lightweight, low-latency TCP firmware that could tolerate dropouts in industrial networks. Ensuring immediate execution of security commands and designing hardware suitable for 24/7 operation were the main challenges of the first version.
Goals (Features):
SP23 focused on simple, reliable integration: network communication via TCP only, a straightforward on-panel UI, and dependable execution of security and fire suppression scenarios. This version did not include Link/Status/Data indicators—I aimed to deliver the essentials with maximum stability.

Battery Monitor – Version BM20
What challenges does this project solve:
In emergency power systems, battery health is critical, yet it’s usually checked periodically and manually—which is time-consuming and increases the risk of sudden system failure. I designed the Battery Monitor BM-20 to solve this fundamentally: a system that can monitor 20 batteries simultaneously and in real time, sending data directly to the monitoring center. This way, technical teams can detect declining health or capacity before problems occur and prevent outages.
What challenges did I face during development:
The main challenge was achieving millivolt-level voltage measurement accuracy across 20 channels simultaneously without noise, ground drop, or interference affecting precision. To address this, I used an isolated sampling circuit with a precise common reference and carefully engineered the grounding and analog paths. Additionally, synchronizing data transmission across three different protocols (SNMP, Modbus, and a web service) without increasing processing load required an optimized software architecture. Long-term tests under varying temperature and load conditions were conducted to ensure 24/7 operational stability. Ultimately, the BM-20 achieved a balance between laboratory-grade accuracy and industrial robustness.
Goals (Features):
The primary goal in designing the BM-20 was to create a smart, continuous monitoring system for UPS batteries. The device measures each cell’s voltage individually and transmits data via three channels:
* SNMP protocol for network monitoring systems
* Built-in web service for browser-based viewing and configuration
* Modbus TCP for integration with industrial systems and RTUs
With dual power input support, full input isolation, and noise-resistant design, it’s suitable for data centers, substations, and UPS rooms. The collected data can be fed into AI algorithms to accurately predict remaining battery life.

Battery Monitor – Version BM2
What challenges does this project solve:
In many smaller projects or local backup systems, there’s a need to monitor the voltage of a single battery, but most available equipment for such use cases is overly complex or expensive. I designed the Battery Monitor BM-2 to address this need—a simple, accurate, network-oriented system that continuously monitors a single battery and sends information over the network to monitoring systems. It’s ideal for small UPS rooms, communication racks, or local emergency power systems and, by eliminating the need for complex equipment, makes battery monitoring faster and more cost-effective.
What challenges did I face during development:
The main challenge in designing the BM-2 was combining high-accuracy voltage measurement with a very compact, low-power design. Due to the small PCB and thermal constraints, selecting low-noise, high-efficiency components was critical. At the same time, all the networking features of larger models (like the BM-20) had to be implemented in a lighter, lower-memory firmware. On the software side, concurrent communication over TCP and UDP was managed with minimal CPU usage. Long-term testing under high temperature and environmental noise was also conducted so the device could operate 24/7 without needing resets or recalibration. The result is a small but professional product that delivers the same accuracy and reliability as multichannel versions in a minimal package.
Goals (Features):
The aim of the BM-2 design was to build a compact version of the Battery Monitor series that offers the same communication capabilities as larger models in a smaller form factor. The device measures the voltage and status of a single battery in real time and sends data to the monitoring center via TCP, UDP, and SNMP protocols. Its industrial design, rugged enclosure, and quick installation make the BM-2 highly practical for tight spaces or projects with many single-channel batteries. Front-panel status indicators (Power, Status, Link) enable quick troubleshooting for technicians, and its integration with smart monitoring systems makes long-term analysis and logging straightforward.

Networked Modbus Temperature and Humidity Sensor – Model TH1-ESR2M
What challenges does this project solve:
In many industrial and facilities environments, simultaneous high-accuracy temperature and humidity monitoring with remote control capability is crucial. I designed this networked temperature and humidity sensor precisely for that purpose—so it can monitor environmental conditions in real time without a separate control system and activate control outputs when thresholds are exceeded. With simultaneous support for LAN and Modbus RTU, it integrates easily into existing monitoring systems and enables both local and remote control.
What challenges did I face during development:
The main challenge was designing the sensing circuit and calibrating it for stability across a wide temperature range. Selecting a sensor with both high accuracy and resilience to harsh conditions required extensive testing in environments with high/low humidity and temperature. In addition, running LAN and Modbus concurrently on a small board—without inducing noise or interference between analog and digital sections—required precise routing and logical isolation. Passing environmental tests and meeting industrial requirements, including voltage fluctuations and electromagnetic interference, were other demanding phases that ultimately resulted in a reliable, standards-compliant product.
Goals (Features):
My goal was to build a precise, reliable industrial sensor that operates across a wide temperature range from −40° to +120°C and remains stable in harsh industrial settings. The device includes two independent relay outputs for ventilation, heating, or alarms. Connectivity is provided via LAN and RS-485, allowing use on modern IP networks as well as traditional industrial communication lines. A rugged enclosure, high sensor accuracy, and easy configuration through the on-panel menu make this sensor suitable for server rooms, greenhouses, the food industry, and industrial spaces.

What challenges did I face during development:
Aligning the new industrial design with the same enclosure dimensions as the previous version was challenging. While maintaining mechanical compatibility, the circuit had to be redesigned and communication paths optimized. Endurance tests under high humidity and severe temperature fluctuations were conducted for final product validation.
Goals (Features):
The enclosure in this version is similar to the second version but with a more industrial look and new color scheme for faster identification. The internal circuitry was redesigned to increase measurement accuracy and to make the sensor respond faster to sudden changes in temperature and humidity. On the software side, the firmware was rewritten and the issues from the previous version were fixed.

Modbus Buried Soil Moisture Sensor – Model SM4-ECO
What challenges does this project solve:
After producing the SM3 version, there was a need for a sensor that could be buried at soil depths (up to 50 cm) and measure the moisture of the lower layers. The goal in designing the SM4-ECO was to develop exactly this capability so that more accurate and stable data could be obtained for irrigation control in agricultural fields.
Goals (Features):
* Measures soil moisture at depths up to 50 cm
* Communication via Modbus RTU (RS-485)
* Suitable for buried applications in agricultural fields and orchards
* Special buried probe design with higher measurement accuracy than the SM3 version
* Fully waterproof for stable operation in humid environments
* Housing resistant to water ingress, mud, and environmental factors
* Can connect to PLCs, RTUs, and smart irrigation systems
What challenges did I face during development:
There were two main challenges in developing the SM4-ECO:
First, designing a probe that could be buried at depth without suffering corrosion or measurement error over time. Second, achieving complete sealing and resistance to moisture ingress, since this sensor must operate underground for years.
To solve these challenges, I used corrosion-resistant materials, resin sealing, and a multi-layer structure so the sensor would be fully protected against soil pressure and moisture. The result was a stable and robust sensor that, with higher accuracy, became a reliable replacement for the previous version and improved the performance of smart irrigation systems.

Goals (Features):
* Measures relative soil moisture as a percentage (%RH)
* Communication via RS-485 using Modbus RTU protocol
* Suitable for use in greenhouses, farms, and smart irrigation systems
* Probe resistant to moisture and soil minerals
* Easy installation at various soil depths
* Can connect directly to PLC, DCS, and RTU systems

What challenges did I face during development:
The main challenge was maintaining accuracy while reducing cost. To this end, a newer yet more economical sensor was used and the electronic circuit was simplified. Long-term stability testing and noise control on long RS-485 lines were also key stages of development.
Goals (Features):
In the second version, the focus was on price optimization, removing non-essential features, and ease of installation. A new enclosure was designed to enable faster and cheaper production. The temperature and humidity sensor sent data via Modbus RTU, and two LEDs were provided to indicate status and communication. This version became the mechanical design basis for subsequent generations.

3-Digit Modbus Display – 20×10 – Model D3-2010
What challenges does this project solve:
In many industrial environments, important data such as temperature, humidity, or pressure is typically only visible in central monitoring systems, and operators on site don’t have quick access to this information. My goal in designing the D3-2010 three-digit Modbus display was to receive critical data directly from the Modbus RTU network and display it instantly and clearly in the field. This allows the operator to see the status of key parameters at a glance, without a computer or HMI—even from a long distance and under intense lighting conditions.
Goals (Features):
This three-digit display is designed with large character height and very powerful LED brightness so it remains fully readable from over 50 meters away and under direct sunlight.
Key capabilities include:
Support for Modbus RTU (RS-485) to receive data from sensors or controllers
Display of positive and negative numbers with precision up to 0.1 units
Ability to choose from 8 different display and status modes to match diverse applications
Rugged body with an aluminum bezel suitable for industrial and semi-industrial environments
This model can be configured to display temperature (TEMP), humidity (HUM), carbon dioxide (CO2), or wind speed (WS), and it is designed to connect directly to the network in environmental monitoring or industrial automation projects.
What challenges did I face during development:
The biggest challenge in this project was maintaining readability under direct sunlight and from long distances. To achieve this, I used high-intensity LEDs and designed a constant-current driver system so brightness remains stable across different ambient lighting conditions.
Another challenge was managing noise and ensuring RS-485 communication stability over long distances, which was addressed with protective circuitry and a communication filter. To prevent visual errors at various angles, the LED emission angle and the optical filter of the front panel were carefully tuned.
In the end, the product meets the needs of industrial environments both technically and visually: simple, readable, and reliable under any lighting conditions.

Industrial electrical panels typically have a large number of digital signals that must be monitored simultaneously and transferred to the control system. My goal in designing the DIM64 card was to transmit a large number of isolated digital inputs centrally over a Modbus RTU network, without the need for multiple, costly wiring runs.
Goals (Features):
* 64 isolated, protected digital inputs
* Support for Modbus RTU (RS-485)
* Software addressing for multiple cards on a single network
* Independent isolated power supply to prevent interference
* 12 V sampling voltage (customizable up to 24 V)
* DIN-rail design for easy panel installation
* Status LED for each input for fast troubleshooting
What challenges did I face during development:
The most important design challenge was managing noise and interference across 64 input channels, which is prevalent in industrial environments. To address this, isolated design and protective filters were used on each channel. Another challenge was integrating a large number of inputs on a board with limited size. Ultimately, DIM64 became a powerful industrial input card that laid the groundwork for subsequent generations in this family.

The goal of designing the M44 card was to build a compact module with 4 isolated digital inputs and 4 relay outputs so it could transmit commands and feedback to the central system (such as a PLC or RTU) over a Modbus RTU network.
Goals (Features):
* 4 isolated digital inputs for receiving sensor or switch status
* 4 relay outputs for controlling equipment (fans, pumps, heaters, etc.)
* Support for Modbus RTU (RS-485) network
* Suitable for greenhouses, treatment plants, oil and gas industries, and production lines
* Reduced cabling volume and increased installation speed
* Software addressing capability for multiple cards on a single network
* LED indicators for input and output status
What challenges did I face during development:
In designing the M44 version, one of the main challenges was managing noise on isolated inputs and outputs to ensure precise, error-free operation in noisy industrial environments. Achieving stability in supply voltage and relay output power also required multi-stage design and thermal testing.
Another goal was to create a module that, in large industrial projects, could handle part of the control process without complete dependence on the main PLC. Ultimately, the M44 became a module that can be easily installed in control panels and provides stable communication on a Modbus network.

Heater Controller and Protector – Model H32
What challenges does this project solve:
In industrial and agricultural environments such as poultry farms or greenhouses, diesel heaters often operate without precise protection and control systems, which is one of the main causes of fires and thermal damage. The goal of designing the H32 heater protection controller was to intelligently and safely control heater operation over an industrial Modbus network. By monitoring temperature and power status, this device turns the heater on and off at the right time, and in case of a fault, it automatically shuts the system down to prevent any incident.
What challenges did I face during development:
The primary challenge in designing the H32 was controlling the weak drivers of diesel heaters, which, due to current fluctuations and unstable structure, were difficult to command. To address this, a dedicated isolated driver system and protective filter were designed so control signals would be transmitted without error.
Additionally, coordinating manual and automatic modes and managing simultaneous alarm signaling and emergency shutdown required precise software design and a dedicated protection algorithm.
Ultimately, the H32 succeeded in becoming a smart and reliable module that replaces traditional heater control methods and plays an effective role in increasing the safety of industrial and agricultural heating systems.
Goals (Features):
* Full control of diesel heaters via Modbus RTU network
* Two operating modes: manual and automatic
* Ability to detect abnormal conditions and issue audible alarms
* Adjustable temperature ranges and protective operation settings
* Industrial design suitable for installation in electrical panels
* Suitable for poultry farms, greenhouses, workshops, and enclosed industrial spaces
* Reduced fire risk through automatic shutdown in critical conditions

Power Management – 2-Channel – Model EPM2
What challenges does this project solve:
In control and instrumentation systems that operate 24/7, even the smallest power outage can cause the entire process to fail or lead to loss of critical data. The goal of designing the EPM2 emergency power management module was to fully automate the switching process between power sources without human intervention. This device intelligently monitors two adapter sources and, if one fails, immediately switches the second source into the circuit. If both sources go offline, the system automatically connects to an emergency UPS or backup battery to maintain power stability for critical equipment.
Goals (Features):
The EPM2 module is designed with a dual-channel architecture for monitoring and managing input power.
Key features include:
* Two independent adapter inputs (RTU and Reserve) with automatic source switching
* Support for battery/UPS to supply power in critical conditions
* LED indicators for each source status and real-time system operation feedback
* Feedback signal output to notify the RTU or central controller
* Rugged, compact design for DIN-rail installation in electrical panels
* Noise-free operation with ultra-low switching delay to maintain stability in sensitive circuits
This device is designed for applications where power continuity is critical — including data centers, industrial automation, environmental monitoring systems, and process control.
What challenges did I face during development:
The primary challenge was designing a switching circuit with extremely low transfer time and no momentary voltage drop. The handover between sources had to occur within a few milliseconds so sensitive systems would not reset or fault.
Another challenge was managing heat and voltage drop during load transfer between sources, which was resolved with precise isolation circuitry and an optimized power path.
On the protection side, adding anti-noise filters and surge protection ensured the EPM2 could operate safely and stably even in noisy industrial environments.
Ultimately, the EPM2 became a simple yet vital tool for ensuring power continuity in industrial control systems.

What challenges does this project solve:
In industrial and sensitive environments such as server rooms or cold storage, precise control of temperature and humidity is critical. The first version of this sensor was designed for projects requiring high accuracy and special safety. The main focus was on building a highly reliable device that is resistant in hazardous environments and can continuously send environmental data to monitoring systems.
Goals (Features):
The initial version was built with an impact-resistant enclosure and explosion-proof (Ex-proof) standard so it could be used in high-risk environments. On the software side, it also offered more advanced capabilities than economic versions, such as intelligent data filtering, real-time alerts, and precise calibration settings. Communication was via Modbus RTU (RS-485), and status indicators enabled rapid fault detection.
What challenges did I face during development:

Modbus Temperature and Humidity Transmitter – Model M1
What challenges does this project solve:
In many industrial projects, there is a need to measure temperature and humidity simultaneously and send this data to controllers (such as PLCs or RTUs) via standard signals. The goal in designing the M1 temperature and humidity transmitter was to build an integrated device that, in addition to accurately measuring environmental parameters, provides a 0–10V instrumentation analog output so it can be used directly in control circuits. By adding a display and control keys, the user can also locally set the desired temperature and the operating range for cooling and heating.
Goals (Features):
* Accurate measurement of ambient temperature and humidity
* 0–10V analog output compatible with PLC, DCS, and RTU
* Three-digit seven-segment display for real-time values
* Ability to set temperature setpoint and hysteresis via UP / DOWN / OK keys
* Metal-sheet enclosure resistant to environmental conditions and electromagnetic noise
Suitable for HVAC control systems, server rooms, greenhouses, and production halls.
What challenges did I face during development:
The main challenge in designing the M1 was passing environmental tests. The metal enclosure increased durability and robustness but required precise design to prevent noise from affecting sensitive analog circuits. Additionally, balancing measurement accuracy and stability of the 0–10V output signal in noisy industrial conditions required precise calibration and hardware filtering.
The user interface with control buttons and the seven-segment display was designed so the user can easily change temperature settings without external software.
Ultimately, the M1 was introduced as a reliable, simple, and robust industrial transmitter that became the foundation for newer generations of temperature and humidity sensors.

Modbus Relay Output Card, Model RM1 – Eight-Channel
What challenges does this project solve:
In projects like greenhouses, water and wastewater stations, and distributed control systems, there’s always the problem of long cabling to carry commands from the central panel to the equipment. My goal in designing the RM1 relay output card was to issue on/off commands directly over a Modbus RTU network so that the need for long wiring would be eliminated and equipment control would become simpler and more reliable.
Goals (Features):
In this project, the main focus was on building an industrial relay card with network communication capability.
This card has 8 isolated 10A outputs and can communicate directly with a PLC, RTU, or DCS.
The circuit was designed to be simple while delivering reliable performance and high durability in industrial environments.
What challenges did I face during development:
The most important challenge was complete isolation of inputs and outputs and designing the circuit in a limited space. To maintain safety and prevent noise on industrial lines, I used opto-isolators and isolated power supplies. After multiple redesigns and thermal testing, I arrived at a stable and robust module that became the foundation for later versions.

Rack Power Distribution (Power Distribution Unit – PDU)
What challenges does this project solve:
One of the main issues in server racks is the safe, precise control and distribution of power across different equipment. In many data centers, the lack of real-time monitoring of each server’s current draw leads to overload risks or sudden shutdowns. My goal in designing this device was to create an intelligent system for per-outlet power management and monitoring so we can both optimize energy consumption and enhance the safety of the power infrastructure.
What challenges did I face during development:
One of the biggest challenges was handling high current within the limited space of a rack. Designing the power circuitry to control sixteen-amp currents across eight channels without generating excess heat or electrical noise required careful component selection and principled routing. Additionally, aligning the current measurement subsystem with the networked control system—so it would be both fast and accurate—was a key development point. Ensuring stable 24/7 operation was also a primary concern during final testing.
Goals:
The Power Distribution Unit I designed provides control and monitoring over eight independent sixteen-amp channels. Each outlet includes current measurement and network connectivity so we can remotely view the status of each channel, measure consumption, and, if needed, turn that outlet—or even the associated server—off or on. This device is built for data centers and industrial racks to deliver precise, safe power management through a web-based control panel.

MIFARE Gate Controller
What challenges does this project solve:
In tourism and transportation projects, the main bottleneck is entry management: authentication must be fast, the card’s payment/credit must be checked, and the gate must open and close without delay. I designed the “MIFARE Gate Controller” to be the link between MIFARE card readers and rotary/barrier gate mechanisms; it stably handles high-traffic throughput while staying synchronized with the central system for settlement and reporting. The result is shorter queues, elimination of manual errors, and centralized, reliable access control and revenue management.
What challenges did I face during development:
The primary challenge was ensuring fast, stable response amid heavy electrical noise from gate motors; to address this, I implemented segregated power/signal routing, proper isolation and filtering, and snubbers for the relays. Data security and protection of MIFARE keys also had to be ensured, and transactions must not be lost during network outages; therefore, I developed online/offline logic, event buffering, and secure synchronization. Reader fault management, input debouncing, watchdog, and automatic recovery were also added so the gate operates error-free under heavy traffic—even with supply fluctuations or interference. The result is a controller compatible with the electronic payment standards of the contracting company and ready for field installation in metro stations and tourist pathways.
Goals (Features):
My goal was to build an industrial controller compatible with existing infrastructure. The board accepts inputs from MIFARE readers and uses multiple isolated relays to control gate actuators; lights and buzzer are managed here as well. For station networking, I provided RS-485 serial communication so multiple gates can be daisy-chained to the central system, and if the link goes down, the device continues offline with whitelist/blacklist and time profiles. Other capabilities include event logging, anti-passback, access limits, and periodic synchronization with the server. A 12/24 V supply, ESD/noise protections, and low-latency firmware design ensure uninterrupted operation in metro environments and tourist venues.

High-Voltage AC I/O Card
What challenges does this project solve:
For controlling single-phase equipment in industrial environments, you typically need an I/O card that safely monitors 220 VAC inputs, reliably switches 220 VAC outputs, and integrates with upstream systems. I built this “High-Voltage AC I/O Card” to be exactly that middle layer: it reports the status of 8 AC inputs to the network in real time and commands 8 relay outputs; moreover, in emergency scenarios, it runs internal protection logic without relying on the central system to protect equipment and operators.
What challenges did I face during development:
The biggest challenge was working with mains voltage and ensuring safety: creepage/clearance distances, selecting suitable optocouplers and relays, snubbers to reduce arcing and noise, and a power supply design that stays stable against fluctuations and surge. On the EMC side, filtering and segregated power/control routing were necessary to prevent false input triggers. In the firmware, I implemented definitive, low-latency responses to Modbus and TCP commands, a watchdog, and fail-safe modes so that on link loss, local protection logic remains active. Thermal testing and relay endurance tests were performed to ensure the card is reliable for continuous industrial operation.
Goals (Features):
My goal was to build a reliable industrial I/O module that connects easily to PLC/SCADA over both Ethernet and Modbus RTU. The card provides 8 isolated 220 VAC inputs with filtering and robust state detection, and 8 relay outputs with inrush tolerance and anti-spark snubbers. Internal logics such as delayed alarms, emergency shutdown, safe restore, and automatic scenarios on power dips/fluctuations are implemented. On-board AC power supply, full isolation between power and signal sections, standard Modbus register mapping, and event reporting simplify installation and operation.
