Abstract

In a sensor device for detecting moisture on a pane comprising at least one transmitter which emits light which is reflected at the pane and received by at least one receiver, an optical system is provided between the transmitter and the receiver, which brings about a multiple reflection between the pane and the optical system. A particularly good measurement is thereby made possible.
