WSS-03 is a RS485 Air Quality sensor. It can monitor CO2, PM2.5 and PM10 at the same time.

WSS-03 uses weather proof shield which 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 WSS-03 RS485 interface to WSC1-L. The weather station main processor WSC1-L can detect and upload the environment CO2, PM2.5 and PM10 to the IoT Server via wireless LoRaWAN protocol.
