DRAGINO LoRa Temperature Sensor Node
LSN50-v2-S31B-EU868
overview
The Dragino LSN50v2-S31B is a LoRaWAN temperature and humidity sensor for Internet of Things solutions. It is used to precisely measure the ambient temperature and relative humidity and then upload it to the IoT server via LoRaWAN wireless protocol.
The SHT31 temperature and humidity sensor used in the LSN50v2-S31B is a fully calibrated, linearized and temperature compensated digital output from Sensirion that offers high reliability
and long-term stability. The SHT31 is housed in a waterproof, condensation-proof housing that enables long-term use.
LSN50v2-S31B supports temperature and humidity alarms, which notify the user immediately.
LSN50v2-S31B is powered by a 8500mAh Li-SOCI2 battery, which is designed for long-term use up to 10 years. (The actual battery life depends on the use environment and upgrade period, please check the related Power Analyze report).
Each LSN50v2-S31B is preloaded with a set of unique keys for LoRaWAN registration, register these keys to local LoRaWAN server and it will automatically connect after power on.
