GCB-MSYS1-V1.5
The General Control board V1.5 is a versatile industrial-grade gateway/datalogger designed for dual-role Modbus communication. It operates as a Modbus Master and Modbus Slave using two MAX485 modules. As a master, it reads sensor data from Modbus slave devices, timestamps it using an RTC module, and logs it to an SD card. As a slave, it can respond to incoming Modbus queries. It also has a DHT11 sensor for device temperature monitoring, and it is expandable for cloud or local network connectivity.
Key Features
- Dual-role: Simultaneous Modbus Master and Slave operations.
- SD card logging of timestamped sensor data.
- Real-Time Clock (RTC DS1307) for time-accurate logging.
- DHT11 for device temperature and humidity monitoring.
- SDI-12 interface.
- Watchdog Timer for system reliability.
- Multitasking with FreeRTOS (ESP32) & Modular code structure for scalability.
Connectivity & Networking Capabilities
The General Control Board V1.5, built on the ESP32S platform, features advanced wireless communication options for seamless integration into modern industrial and IoT systems. These connectivity features support local and remote data access, device configuration, and cloud integration.
Wi-Fi Networking
We offer comprehensive industrial engineering services including process design, facility layout, and quality control. Our team of experienced engineers has the expertise to optimize your operations and improve your bottom line.
- Remote monitoring and control via web servers or mobile apps (e.g., Blynk,Azure, MQTT dashboards)
- OTA (Over-the-Air) firmware updates to ensure up-to-date functionality
Bluetooth Low Energy (BLE)
The board supports BLE , allowing:
- Low-power communication with smartphones or BLE-enabled gateways
- Initial configuration and diagnostics through mobile applications
- Short-range peer-to-peer communication where Wi-Fi is unavailable
ESP-NOW Protocol
ESP-NOW is an efficient, connectionless protocol ideal for short bursts of data between ESP32 devices. It allows:
- Low-latency communication between multiple boards
- Reduced power consumption due to minimal overhead
- Secure communication with peer-to-peer encryption support
