LTC1-LB-868M: LoRaWAN Temperature Transmitter Node

The Dragino LTC1/LTC2-LB LoRaWAN Industrial Temperature Transmitter is designed to monitor temperature in various environments. It supports reading PT100 probes, converts the value to temperature, and sends it to the IoT server via LoRaWAN protocol. The LTC1-LB supports one temperature monitoring channel. By pressing the button, the data packet can be sampled and uploaded immediately. The LTC1/LTC2-LB supports Datalog (data logging) function. Users can retrieve sensor values via LoRaWAN downlink command.

The LTC1/LTC2-LB supports configuration via BLE (Bluetooth Low Energy) and OTA (Over-The-Air) wireless update, which makes it easy to use. The LTC1/LTC2-LB is powered by an 8500 mAh Li-SOCI2 battery or a solar panel with a lithium-ion battery; it is designed for long-term use for up to several years.
