--WSS-22 is a RS485 wind speed and wind direction monitor designed for weather station solution.
++* Supply voltage: 5~~24V DC
++* Wind speed measurement range: 0～30m/s; 0～50m/s; 0～60m/s;
++* Wind direction measurement range: 0～360°
++* Starting wind speed: ≤0.3m/s
++* Accuracy: ±(0.3+0.03V) m/s, ±1°
++* Output signal: RS485 (standard Modbus-RTU protocol)
++* Working environment: Temperature: -30℃～70℃; Humidity: ≤100%RH
++* Storage environment: Temperature: -30℃～70℃; Humidity: ≤100%RH
--WSS-22 shell is made of polycarbonate composite material, which has good anti-corrosion and anti-corrosion characteristics, and ensure the long-term use of the sensor without rust. At the same time, it cooperates with the internal smooth bearing system to ensure the stability of information collection

--WSS-21 RS485 Rain Gauge is used in meteorology and hydrology to gather and measure the amount of liquid precipitation (mainly rainfall) over an area.
++== 9.1 Overview and Spec ==
--WSS-21 uses a tipping bucket to detect rainfall. The tipping bucket use 3D streamline shape to make sure it works smoothly and is easy to clean.
++[[image:image-20250505184214-19.png||height="324" width="320"]]
--The tipping bucket of WSS-01 is adjusted to the best angle. When installation, user only needs to screw up and adjust the bottom horizontally.
--WSS-21 package includes screw which can be installed to ground. If user want to install WSS-21 on pole, they can purchase WS-K2 bracket kit.
