Mobile Weather Sensor

The SurfaceScan is a vehicle mounted mobile weather sensor. The sensor monitors road surface temperature, air temperature, relative humidity and dewpoint, as well as displays live readings using a dash mounted graphical display. The SurfaceScan can be used to detect freezing temperatures on the pavement to determine where frost or black ice may form if precipitation occurs.
