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 them to the IoT server via the wireless LoRaWAN protocol.
The SHT31 temperature and humidity sensor used in the LSN50v2-S31B is a fully calibrated, linearized and temperature-compensated digital output from Sensirion, which ensures high reliability
and long-term stability. The SHT31 is housed in a waterproof, condensation-proof housing that allows for long-term use.
LSN50v2-S31B supports temperature and humidity alarms that notify the user immediately.
LSN50v2-S31B is powered by an 8500mAh Li-SOCI2 battery, designed for long-term use of up to 10 years. (The actual battery life depends on the usage environment and update period, please check the related Power Analyze report).
Each LSN50v2-S31B is pre-loaded with a set of unique keys for LoRaWAN registration, register these keys to local LoRaWAN server and it will automatically connect after power on.
