Abstract
A sensor device is described for detecting wetting, in particular rainfall and soiling, on a windshield that has at least one transmitter and at least one receiver for the light emitted by the transmitters where transmitters and receivers are arranged at the corner points of an imaginary triangle or parallelogram. As a result, the outside dimensions of the sensor are reduced, and the ratio of sensitive area to base area of the sensor is improved.
