WSS-03 is an RS-485 air Quality sensor. It can monitor CO2, PM2.5, and PM10 at the same time.
WSS-03 uses a weatherproof shield that can make sure the sensors are well protected against UV & radiation.
WSS-03 is designed to support the Dragino Weather Station solution.
Users only need to connect the WSS-03 RS485 interface to WSC1-L, WSC2-LB. The weather station's main processor, WSC1-L, can detect and upload the environment's CO2, PM2.5, and PM10 to the IoT Server via the wireless LoRaWAN protocol.
