The customer required to develop a compact, battery-powered, high-precision temperature measurement system with data logging and long-range wireless connectivity for remote monitoring and control.

We built a LoRa Precision Sensor with on-board memory for storing measurements and for transmitting data over LoRa/LoRaWAN.

The device supports remote and automatic controls and provides industrial interfacing via RS485.

Core hardware interfaces include a RAK3172 LoRa module, PT1000 precision temperature sensor, flash memory, RS485, opto-relay, and a dedicated sensor measurement controller.
