A moisture detection system includes an electrical conductor disposed on a surface of a substrate, an oscillator for outputting an oscillator signal at a predetermined amplitude and a predetermined frequency, and a resonator circuit coupled to the electrical conductor and responsive to the oscillator signal for outputting a resonator signal having an amplitude related to a resonant frequency of the electrical conductor. A filter circuit responsive to the resonator signal can output a rectified and filtered signal, and an analog-to-digital converter responsive to the rectified and filtered signal can output a digital signal related to the rectified and filtered signal. A sensor can be provided having a property that varies as a function of a temperature at or adjacent the electrical conductor. A controller can be responsive to the digital signal and the property of the sensor for causing another system to operate as a function thereof.

A moisture detection system includes an electrical conductor disposed on a surface of a substrate. The electrical conductor has a resonant frequency that varies as a function of an amount of moisture present adjacent the electrical conductor. An oscillator outputs an oscillator signal at a predetermined amplitude and a predetermined frequency. A resonator circuit is coupled to the electrical conductor and is responsive to the oscillator signal and the resonant frequency of the electrical conductor for outputting a resonator signal having an amplitude related to the resonant frequency of the electrical conductor. A filter circuit rectifies and filters the resonator signal and provides it to an analog-to-digital converter which outputs a digital signal related to the rectified and filtered resonator signal. A controller is responsive to the digital signal for causing a system associated with the substrate to operate in accordance with the digital signal.
