Abstract

The sensor has a printed circuit board (1) with electrical conductor tracks (2-4) and connection points to apply a supply voltage (UB) and conduct a sensor signal (US) to evaluation electronics (8). At least two conductor tracks (3,4) are connected at different voltages in a defined area (6) on the circuit body and are short-circuited or interrupted by moisture, to generated a characteristic sensor signal for delivery to the evaluation unit.
