Description
The Dragino WSS-21 RS485 Rain Gauge is a weather monitoring instrument to monitor rainfall. WSS-21 uses a 3D streamlined tipping bucket to detect rainfall that works smoothly and is easy to clean.
WSS-21 is designed to auto-support the Dragino Weather station solution, simply needing to connect the WSS-21 RS485 interface to the weather station main processor WSC2-L, which can auto-detect and upload the rainfall to the LoRaWAN Server.
The tipping bucket of WSS-21 is adjusted to the best angle, so during installation, users need only to screw up and adjust the bottom horizontally. The WSS-21 package includes a screw for installation to the ground; a WS-K2 bracket kit (purchased separately) enables pole installation.
