LTC2-LS LoRaWAN Temperature Transmitter Node 868MHz

The LTC2-LS LoRaWAN Temperature Transmitter Node is an industrial sensor specifically developed for monitoring temperatures in different environments with solar power supply. It supports PT100 probes and can transmit the recorded temperature values to IoT servers via the LoRaWAN network. With its datalogging feature, temperature values can be stored and retrieved over LoRaWAN. This robust sensor node, housed in a weatherproof enclosure, is ideal for outdoor use and is powered by solar energy and an integrated battery, ensuring long operating time. Configuration is conveniently done via Bluetooth or wireless OTA updates, allowing the LTC2-LB to be easily adapted to different operating 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 predestined for long-term operation in demanding environments.

Each sensor comes preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server, and the sensor automatically establishes a connection after being powered on when network coverage is available.
