LSN50 v2 S31 LoRaWAN Outdoor Temperature & Humidity Sensor

LSN50 v2 S31 LoRaWAN Outdoor Temperature & Humidity Sensor

$51.00

The Dragino LSN50v2-S31 is a LoRaWAN Temperature and Humidity Sensor for Internet of Things solutions. It is used to measure the surrounding environment temperature and relative air humidity precisely, and then upload – via a LoRaWAN gateway – to any IoT server via LoRaWAN wireless protocol.

Each LSN50v2-S31 is pre-loaded with a set of unique keys for LoRaWAN registration. Register these keys to any LoRaWAN server and the sensor will auto connect after power on.

Product Description

The temperature & humidity sensor used in the LSN50 v2 S31 is the Sensirion SHT31, which has a fully calibrated, linearized, and temperature compensated digital output. It provides a strong reliability
and long-term stability. The SHT31 is fixed in a waterproof anti-condensation casing for long term use.

The LSN50 v2 S31 supports a temperature and humidity alarm feature, allowing the user to set a temperature alarm for immediate notification.

The LSN50 v2 S31 is powered by an 8500mAh Li-SOCI2 battery. It is designed for long term use up to 10 years. (Battery life depends on the usage environment and update period. Please check the related Power Analysis report)
