Abstract

A moisture detection system includes a moisture detector having a first electrical conductor (6), a first substrate (16) having the first electrical conductor disposed on one surface thereof, a spacing layer (14) coupled to the other surface of the first substrate, a second substrate (12) having one surface thereof coupled to a surface of the spacing layer opposite the first substrate, and an electrically conductive layer (218) disposed on a surface of a substrate opposite the spacing layer. A second electrical conductor can be disposed on the same surface of the first substrate as the first electrical conductor. The first and second electrical conductors can define interdigitated fingers. Circuitry is provided for stimulating the first electrical conductor (6) with a predetermined frequency oscillator signal and for outputting a control signal that is responsive to the response of the first electrical conductor (6) to the oscillator signal and an amount of moisture adjacent the first electrical conductor (6).
