WSS-04 is a RS485 rain / snow detect sensor. It can monitor Rain or Snow event. 

WSS-04 has auto heating feature, this ensures measurement more reliable.

WSS-04 is designed to support the Dragino Weather station solution.

Users only need to connect WSS-04 RS485 interface to WSC1-L. The weather station main

processor WSC1-L can detect and upload the SNOW/Rain Event to the IoT Server via wireless LoRaWAN protocol.
