With a sensor device for recording moisture on a window pane with a transmitter and a receiver and an optical unit arranged between the transmitter and the receiver, wherein the optical unit includes an optical input unit facing the transmitter, an optical output unit facing the receiver and a coupling-in and coupling-out region on the side of the window pane, the coupling-in and coupling-out region is optically separated from the optical input unit and the optical output unit such that the electromagnetic waves emitted by the transmitter are refracted. A particularly compact constructional design is achieved thereby.
