Abstract
In a rain sensor, a sensor field is arranged between two windshield wiper blades which lie one above the other on a windshield. The sensor field is thus located outside of the field of view of the driver and is wiped by the lower windshield wiper blade. The sensor field is connected to an evaluation circuit arranged on a wiper motor by connecting lines which pass around the lower wiper blade.
