RAIN SENSOR
Application
The rain sensor is a sensor that detects precipitation such as rain and snow. The sensitivity is adjustable. The automatic heating prevents icing or condensation and speeds up drying. In the most sensitive setting, the unit is also suitable for detecting fog. They are used in agriculture and greenhouses, in building management systems, weather stations or for controlling ventilation hatches and skylights.
