The Dragino LTC2 sensor node is a high-precision solution for temperature monitoring in demanding environments. It supports PT100 probes and securely transmits measured values to IoT servers via LoRaWAN, NB-IoT or LTE-M. Thanks to Bluetooth Low Energy (BLE) for configuration and over-the-air (OTA) updates, commissioning is straightforward. The device is designed for long-term use and is powered either by an 8500 mAh Li/SOCl₂ battery or a solar panel with integrated Li-ion battery.
