Abstract

A sensor device for detecting the degree of wetting and/or soiling of a pane or windshield arranged in a motor vehicle includes individual radiation guide elements integrally molded onto a wall of a housing to be separated from one another by a blocking element of the wall. This reduces the amount of ambient radiation from the environment. A radiation emitter and a radiation receiver are structured as SMD components which are arranged on a circuit board carrier. The sensor device created in this way has a simple and compact design.
