The precipitation sensor ombra W1-R is used to detect precipitation. The signal is further processed e.g. for safety devices to protect hangings (e.g. blinds or awnings).
Precipitation that wets the sensor surface changes the electrical capacitance. A wetted sensor surface means “precipitation”.
To avoid condensation or icing of the sensor, it is heated to the ambient temperature + 2K.
If the sensor surface is wetted, it is heated to ambient temperature + approx. 10K. This results in faster drying.
