    LSN50v2-S31B LoRaWAN Waterproof Temperature and Humidity Sensor

    The Dragino LSN50v2-S31B is a LoRaWAN Temperature and Humidity Sensor for the Internet of Things solution. It is used to measure the surrounding environment temperature and relative air humidity precisely, and then upload to IoT server via LoRaWAN wireless protocol.

    The temperature & humidity sensor used in LSN50v2-S31B is SHT31, which is fully calibrated, linearized, and temperature compensated digital output from Sensirion, it provides strong reliability
    and long-term stability. The SHT31 is fixed in a waterproof anti-condensation casing for long-term use.

    LSN50v2-S31B supports temperature and humidity alarm feature, users can get alarmed for instant notice.

    LSN50v2-S31B is powered by an 8500mAh Li-SOCI2 battery, It is designed for long-term use up to 10 years. (Actually Battery life depends on the use environment, update period. Please check the related Power Analyze report).

    Each LSN50v2-S31B is pre-load with a set of unique keys for LoRaWAN registration, register these keys to the local LoRaWAN server and it will auto-connect after power on.
