++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

--== 9.1 Overview and Spec ==
++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.
--[[image:image-20250505184214-19.png||height="324" width="320"]]
++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.
++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.
--* Rain-receiving port size: Φ200mm; sharp angle of blade: 40°～45°
--* Range: 0～100mm (range is limited to analog signal, RS485 signal is not measured)
++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.
++
++
++== 9.1 Feature ==
++
++* RS485 Rain Gauge
++* Small dimension, easy to install
++* Vents under funnel, avoid leaf or other things to avoid rain flow.
++* ABS enclosure.
++* Horizontal adjustable.
++
++== 9.2  Specification ==
++
  * Resolution: 0.2mm
--* Rain intensity range: 0mm～4mm/min (maximum rain intensity allowed is 8mm/min)
--* Accuracy: ≤±3%
--* Output signal: RS485 (standard Modbus-RTU protocol)
--* Power supply voltage: 5～24V DC
--* Operating temperature: 0℃～70℃ (optional heating function, can be as low as -40℃)
--* Operating humidity: <100% (no condensation)
++* Accuracy: ±3%
++* Range: 0 ~~ 100mm
++* Rainfall strength: 0mm ~~ 4mm/min (max 8mm/min)
++* Input Power: DC 5 ~~ 24v
++* Interface: RS485
++* Working Temperature: 0℃ ~~ 70℃ (incorrect below 0 degree, because water become ICE)
++* Working Humidity: <100% (no dewing)
++* Power Consumption: 4mA @ 12v.
