How It Works

Measurement: The Pt100 RTD sensor measures temperature by converting thermal energy into electrical resistance. The integrated amplifier measures this resistance and converts it to a digital temperature value.

Processing: The embedded microcontroller processes the raw sensor data, applies calibration corrections, and stores historical measurements in local flash memory for data integrity.

Transmission: Data is encrypted and transmitted via LoRaWAN to your network gateway. The adaptive data rate algorithm optimizes battery life while maintaining reliable communication.

Cloud Platform: Temperature data is received by the Controlytics cloud platform, where it's processed, visualized, and made available through our web and mobile applications.
