ABSTRACT:
Apparatus that detects the presence and condition of precipitation on the surface of a pathway. The apparatus has a block of electrically insulative material adapted to be embedded in the pathway with a top surface exposed to precipitation. A sensor is embedded in the block for sensing a physical property of the precipitation to produce a sensor output which is also influenced by a depth of the precipitation. Part of the top surface of the block has a well that is generally curved in outline above the sensor for gathering precipitation for the sensor. Advantageously, the influence of precipitation depth on the sensor is diminished. Other apparatus and methods are also disclosed.
