The Dragino LSN50v2-S31B is a LoRaWAN Temperature and Humidity Sensor for 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.
LSN50v2-S31B supports temperature and humidity alarm feature, user can get alarm for instant notice.
Features:
LoRaWAN v1.0.3 Class A
Measure range -40°C ~ 80°C
LSN50v2-S31B is powered by 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 related

Each LSN50v2-S31B is pre-load with a set of unique keys for LoRaWAN registration, register these
keys to local LoRaWAN server and it will auto connect after power on.
Temperature and humitidy alarm
The temperature & humidity sensor used in LSN50v2-S31B is SHT31, which is fully calibrated,
linearized, and temperature compensated digital output from Sensirion, it provides a strong reliability
and long-term stability. The SHT31 is fixed in a waterproof anti-condensation casing for long
term use.
