SN50V3-LB LoRaWAN Sensor Node 868MHz

The SN50V3-LB is a waterproof LoRa sensor node that operates on the 868 MHz Long Range LoRa technology. This robust sensor node, packaged in a weatherproof housing, is ideal for outdoor use, and is powered by an 8500mAh Li/SOCl2 battery, ensuring long operating time. But the SN50V3-LB is more than just a sensor node. It was designed to facilitate the rapid implementation 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 an exceptionally wide range, high interference resistance, and optimizes power consumption. Equipped with a powerful 48 MHz ARM microcontroller, 256KB flash, and 64KB RAM, the SN50V3-LB is equipped for all types of projects. Moreover, it offers easy connectivity to various sensors via its multiplex I/O ports. The SN50V3-LB has an integrated BLE module that allows comfortable 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 LSN50 from Dragino, offering 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 comes preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the sensor automatically connects after power on, provided network coverage is available.
