US Patent 7295126 Perforated plane moisture sensor

A moisture sensing apparatus, system and method. In general, a surface can be provided, and one or more conductor pairs located in a plane of the surface. Each conductor of the conductor pair(s) is insulated from one another. Water droplets forming on the conductor pair(s) thereby provide a quantifiable measurement of water on the surface. A controller can be electrically connected to the conductor pair(s), wherein the controller provides data indicative of whether or not the conductor pair is shorted.
