Abstract
An embodiment of the present invention provides a surface sensor system comprising a wet/dry sensor assembly, an electrically isolated passive sensor assembly, a thermally adjustable active sensor assembly, at least one temperature sensor, and a data processing device coupled together as a unit positionable adjacent to a surface, such as an outdoor surface. The unit is configured to determine the presence a surface material containing water or a water-based mixture on the surface and the solid or liquid phase of the surface material.
