LTC2-HT2 LoRaWAN Temperature Sensor

The Dragino LTC2-HT2 is an industrial LoRaWAN® temperature transmitter designed for high-accuracy, dual-channel temperature monitoring using PT100 probes. It converts PT100 resistance values into precise temperature readings and transmits the data to an IoT server over the LoRaWAN v1.0.3 Class A protocol.

Powered by a high-capacity 8500mAh Li-SOCl₂ battery, the LTC2-HT2 supports 2–10 years of operation, depending on network conditions and reporting intervals. With factory calibration, BLE/LoRa or UART configuration, battery monitoring, and console-based firmware upgrades, it is well suited for demanding industrial and cold-chain environments.
