SenTec SEM2000 mini automatic weather station can simultaneously monitor multiple optional meteorological parameters: wind speed, wind direction, temperature, humidity, pressure, precipitation, solar radiation, UV radiation, luminance and PM1.0/2.5/10.
Measurement of precipitation adopts advanced small 24GHz Doppler radar,The speed rate of drops is registered with a 24 GHz radar system. By comparison between the speed rate and the size of drops, the quantity of rain or its intensity will be registered. The rain/precipitation type (rain/snow/snow-covered rain/freezing rain/hail) is determined thanks to the speed rate of the rain.
Thanks to the adoption of new technology and design, the structure is more compact and robust. No need to conduct maintenance or calibration after installation.It's very suitable to be integrated into Agrometeorological System.
