D20-LS LoRaWAN Temperature Sensor Node 868MHz with Solar

The D20-LS LoRa module is an 868 MHz long range temperature sensor node for outdoor use, powered by solar energy and an integrated battery. The sensor measures temperatures from -55°C to 125°C with a tolerance of ±0.5°C. This robust sensor node, packed in a weatherproof housing, is ideal for outdoor use and is powered by solar energy and an integrated battery, thus ensuring a long operating duration. The D20-LS is more than just a sensor node. It is designed to enable the rapid implementation of industrial LoRa and IoT solutions. The wireless part of the node is based on the SX1262, which enables the transmission of data over very long distances at low data rates. This ensures exceptionally wide range, high immunity to interference, while optimising power consumption. Equipped with a powerful 48 MHz ARM microcontroller, 256KB flash and 64KB RAM, the D20-LS is prepared for all types of projects. The D20-LS has an integrated BLE module, which allows convenient configuration of the sensor from your mobile phone. It also supports OTA updates via a private LoRa protocol, greatly simplifying maintenance. This sensor node is the third generation of the popular LSN50V2-D20 from Dragino and offers a mature LoRaWAN stack and application software. You can use the pre-installed software for your IoT projects or flexibly adapt the software to different requirements.

Each sensor is pre-loaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the sensor automatically connects upon power-up, if network coverage is available.
