D22-LB LoRaWAN 2-Channel Temperature Sensor Node 868Mhz

The D22-LB from Dragino is an 868Mhz waterproof LoRaWAN sensor node with two temperature sensors. The DS18B20 temperature sensors used measure in a range of -55°C to 125°C with a tolerance of ±0.5°C (max ±2.0°C). A 1.5m sensor cable is connected to the module, terminating in two separate temperature probes. This robust sensor node, packaged in a weatherproof housing, is ideal for outdoor use and is powered by an 8500mA Li/SOCl2 battery, ensuring long operating duration. The D22-LB is more than just a sensor node. It is designed to enable rapid deployment of industrial LoRa and IoT solutions. The wireless part of the node is based on the SX1262, which allows data transmission over very long distances at low data rates. This ensures exceptionally long range, high interference immunity, and optimizes power consumption. Equipped with a powerful 48 MHz ARM microcontroller, 256KB flash, and 64KB RAM, the PS-LB-NA is ready for all types of projects. The D22-LB has an integrated BLE module that allows convenient configuration of the sensor from your mobile phone. It also supports OTA updates via a private LoRa protocol, significantly simplifying maintenance. This sensor node is the third generation of the popular LSN50V2-D22 from Dragino and offers a mature LoRaWAN stack as well as application software. You can use the pre-installed software for your IoT projects or flexibly adapt the software to different requirements. 

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 upon activation if network coverage is available.
