LoRa Gateway S281 is based on LoRa RF technology.It’s mainly used for collecting multiple environmental data distributed in different long range areas and transparent data transmission from device to cloud. With LoRa modulation technology, it’s capable of realizing multiple IO device monitoring, collecting data of temp & humi, intensity of lighting, CO2, wind direction & speed and soil condition.

LoRa communication range is up to 2KM.Built-in LoRa chip SX1278 and GSM/GPRS/3G/4G/RJ45 module work together to achieve remote monitoring and control by sending sensor, PLC, smart meter and other device data to cloud or mobile phone via SMS/2G/3G/4G/Ethernet. Huge field wiring cost will be saved

This wireless data acquisition system comprised of 2 parts, LoRa Gateway S281 and LoRa Nodes. Nodes connect senor, PLC and other devices. The collected data is sent to gateway. Mutual communication between PLC and cloud is done through wireless RF technology. Alarm threshold can be set in gateway so that alarm events can be recorded.
