S31-LS -- LoRaWAN Temperature & Humidity Sensor

Description

The Dragino S31-LB/LS 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. 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 a 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 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 Temperature & Humdity alarm feature, user can set temperature alarm for instant notice. S31-LB /LS supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover. S31-LB /LS supports BLE configure and wireless OTA update which make user easy to use. S31-LB /LS is powered by 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-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on. Common DC Characteristics:
