LTC2-LB LoRaWAN Temperature Transmitter Node 868MHz

The LTC2-LB LoRaWAN Temperature Transmitter Node is an industrial sensor specifically designed for monitoring temperatures in various environments. It supports PT100 probes and can transmit the measured temperature values to IoT servers via the LoRaWAN network. With its data logging function, temperature values can be stored and retrieved via LoRaWAN. The sensor is equipped with a long-lasting 8500mAh Li-SOCI2 battery, enabling years of operation. Configuration is conveniently done via Bluetooth or wireless OTA updates, allowing the LTC2-LB to be easily adapted to different deployment conditions. With up to two temperature channels and a wide measurement range, this sensor is ideally suited for numerous industrial applications. Thanks to its robust design and low power consumption, it is destined for long-term operation in challenging environments.

Each sensor is preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server, and the sensor automatically connects once powered on if network coverage is available.
