DRAGINO LSN50-v2-S31-EU868 LoRa Temperature Sensor

overview

The Dragino LSN50v2-S31 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 temperature and humidity sensor used in the LSN50v2-S31 is the SHT31, 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 to ensure long-term use.

LSN50v2-S31 supports temperature and humidity alarm function, so that the user can receive an alarm for instant notification.

The LSN50v2-S31 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 usage environment and upgrade period, please check the related Power Analyze report).
Each LSN50v2-S31 is preloaded with a set of unique keys for LoRaWAN registration.
