Abstract
The present invention is generally directed toward sensors and associated methods, including surface condition sensors. For example, in certain embodiments sensor can be configured to sense the surface conditions on a road surface and/or an airport surface. One aspect of the invention is directed wet/dry sensors. Other aspects of the invention are directed toward conductivity sensors. Still other aspects of the invention are directed toward sensor packages that include a combination of active and passive sensor technology. Yet other aspects of the invention are directed toward communication systems and methods associated with various sensors.
