The snow sensor utilizes a single temperature sensor and heating element in thermal contact with the sensing surface. The signal from the temperature sensor and the signal from the heating element are input to a standard microprocessor integrated circuit. The microprocessor continuously compares the two signals to accurately assess whether snow is present on the sensing surface. The snow sensor eliminates the requirement for a moving airmass to acurately assess the presence of snow on the sensing surface. The snow sensor does not ingest snow nor require ice formation to operate. The snow sensing surface and the sensor housing are weather and debris resistant. The snow sensor may be mounted in an elevated position or in any suitable location proximate an area to be monitored. The snow sensor of the present invention serves as an integral part of a closed loop control system for numerous snow removal applications.
