The Lufft WS600-UMB is a product in the "WS" family compact weather stations. This station is equipped with a temperature, relative humidity, air pressure and Doppler radar rainfall measurement. The smart rain gauge "sees" whether it is raining or snowing. This rain gauge is maintenance free and is heated against frost. The integrated ultrasonic wind sensor measures wind speed and direction without moving parts. By default, the WS-weather stations include a digital output with Modbus RTU.
