1.Brief Introduction
1.1
Overview
S281 is wireless data ,wireless temperature and humidity acquisition &alarm system. It is based on LoRa radio, mainly used
for multi-point and long-distance distributed temperature and humidity acquisition and transparent transmission from
equipment to cloud platform. LoRa modulation technology is adopted to realize on-site distributed multi-point IO
equipment monitoring and temperature &humidity collection. Communication distance can be up to 1km.Built-in LoRa
SX1278 chip, GSM/GPRS/3G/4G/RJ45 module, S281 can transfer sensor, PLC, smart meter and other data via wireless RF,and
then through SMS/2G/3G/4G/Ethernet Send it to the cloud platform or mobile phone to realize remote monitoring and
control, and solve the problem of on-site wiring.
This system includes LoRa gateway and LoRa slave device.LoRa slave devices connect sensors,PLC and other devices,and
transfer data to cloud,phone App via RF.It realizes the dual communication between cloud and PLC or other devices.When
slave device acquires temperature&humidity data,alarm values can be set by gateway to realize SMS alarm.
