Abstract
An optoelectronic sensor device for detecting precipitation on an outer surface of a transparent pane. The sensor device includes a beam guide attached to an inner surface of the pane and a circuit board offset from the inner pane surface. A beam transmitter is arranged on the circuit board to transmit, along a transmission beam path, a light beam toward the pane via the beam guide. A beam receiver is arranged on the circuit board to receive, along a reception beam path, a light beam reflected from the outer surface of the pane via the beam guide. A circuit substrate, electrically connected to the circuit board, is arranged parallel to the pane between the pane and the circuit board. An installation space separates the circuit substrate from the inner pane surface. A heating device is arranged on the circuit substrate in an area lying outside of the beam paths.
