Description

The Dragino S31-LB/LS 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 the IoT server via LoRaWAN wireless protocol.

The temperature & humidity sensor used in S31-LB/LS 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.

The LoRa wireless technology used in S31-LB/LS allows the device to send data and reach extremely long ranges at low data rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

S31-LB/LS supports the Temperature & Humidity alarm feature, the user can set the temperature alarm for instant notice. S31-LB/LS supports the Datalog feature, it can save the data when there is no LoRaWAN network and uplink when the network recovers.

S31-LB/LS supports BLE configure and wireless OTA update which make users easy to use.

S31-LB/LS is powered by an 8500mAh Li-SOCI2 battery or solar powered + li-on battery it is designed for long-term use up to 5 years.

Each S31-LB/LS is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server and it will auto-connect after powering on.
