Abstract
A sensor arrangement for detecting a wetting, in particular a precipitation and dirt accumulation, on a window ( ) is proposed, with at least one transmitter ( ) and at least one receiver ( ) for the transmitter light ( ) emitted by the transmitters ( ), where the transmitters ( ) and receivers ( ) 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 ( ) and base area ( ) 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.
