ABSTRACT:
A moisture sensor to sense rain on a windshield includes sensor members and leads on the outboard surface of the windshield. The members and leads are uncoated and directly exposed to any moisture accumulation on the sensor. Leads connect the sensor to a controller which includes a signal generator and sensor monitor. The relative spacing between the leads as compared to the spacing between the sensor members is such that the impedance of the sensor when the leads are electrically interconnected by moisture is measurably different from the sensor impedance when said members or said members and leads are electrically interconnected. In response to the latter signal, the windshield wipers are actuated.
