The Dragino LTC2-LB Industrial LoRaWAN Temperature Transmitter is designed to monitor temperature for different environment. It supports to read PT100 probe and convert the value to temperature and uplink to IoT server via LoRaWAN protocol.

LTC2-LB supports Datalog feature. User can retrieve the sensor value via LoRaWAN downlink command.

LTC2-LB supports BLE configure and wireless OTA update which make user easy to use.

LTC2-LB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

Default FW in AS923, but it support US915, AU915 and all 900MHz Frequency by loading different FW, it could also support 868MHz if loading 868MHz FW, but there will be slight 0.5-1dB loss here.
