S31-LB
User Manual
OVERVIEW
The Dragoon S31-LB is a Lora WAN 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 is SHT31, which is fully
calibrated, linearized, and temperature compensated digital output from
Sensation, it provides a strong reliability and long-term stability. The SHT31
is xed in a waterproof anti-condensation casing for long term use.
The Lora wireless technology used in S31-LB 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 supports Temperature & Humidity alarm feature, user can set temperature
alarm for instant notice.
S31-LB supports Data log feature, it can save the data when there is no Lora
WAN network and uplink when network recover.
S31-LB supports BLE configure and wireless OTA update which make user easy to
use.
S31-LB is powered by 8500mAh Li-SOCI2 battery, it is designed for long term
use up to 5 years.
Each S31-LB is pre-load with a set of unique keys for Lora WAN registrations,
register these keys to local Lora WAN server and it will auto connect after
power on.
