| Zusammenfassung: | A sensor device for detecting wetting, in particular rainfall and soiling, on a windshield (
22
) has at least one transmitter (
12
) and at least one receiver (
14
) for the light (
26
) emitted by the transmitters (
12
), where transmitters (
12
) and receivers (
14
) are arranged at the corner points of an imaginary triangle or parallelogram (
16
). Therefore, the outside dimensions (b, l) of the sensor are reduced, and the ratio of sensitive area (
20
) to base area (
16
) of the sensor is improved. |
