Vorrichtung und Verfahren zum Betreiben eines Regensensors

摘要

In a process and device for operating a rain sensor (10), a sensor signal (18, 22) is generated depending on the extent to which a glass pane (11) is wetted. A regulator (16) transmits a regulating signal (28) to the rain sensor (10) as a function of the sensor signal (18, 22) for regulating the sensor signal (18, 22). The sensor signal (18, 22), as well as the regulating signal (28), are evaluated to trigger switching processes of a device.
