A sensor arrangement for detecting a wetting, in particular a precipitation and dirt accumulation, on a window (13) is proposed, with at least one transmitter (14) and at least one receiver (15) for the transmitter light (17) emitted by the transmitters (14), where the transmitters (14) and receivers (15) are disposed on the vertex points of an imaginary trapezoid. As a result, the external dimensions of the sensor are reduced, the ratio of sensitive area (19) and base area (18) of the sensor is improved, and a coherent sensitive area is produced, where there is also space available for a receiving element of an automatic light control.
