Precision Gas Dosing & Multi-Sensor Control System

Droid Technologies designed and developed a precision gas dosing and process control system for accurate regulation of gas flow while collecting data from multiple analog sensors.

The platform was initially based on an STM32F7 and later upgraded to an STM32H7 as the main controller, providing higher processing performance for sensor acquisition, control algorithms, and real-time system management. An ESP32-S3 provides Wi-Fi and Bluetooth Low Energy (BLE) connectivity.

The device supports Ethernet, Wi-Fi, BLE, and USB communication, allowing connection to a PC, local server, or remote monitoring platform for real-time data exchange, analytics, configuration, and process control.

Droid Technologies delivered hardware design, PCB development, embedded firmware, analog sensor integration, gas dosing control, ESP32-S3 wireless integration, Ethernet/USB communication, and complete system testing.
