A device for detecting the presence of water includes a capacitance sensor coupled to a windshield to detect capacitance changes. A multivibrator is coupled to the sensor to translate the detected capacitance change to the frequency domain. A phase-locked loop coupled to the multivibrator produces a phase pulse in response to water causing a change in capacitance and, in turn, a change in the frequency of the multivibrator.
