Abstract
PURPOSE: To perform accurate detection with small power consumption by thawing the fallen snow having been received in a hollow cylindrical case through a heater controlled according to snowfall, counting the number of the water drops falling and detecting the water level of the measuring tube.
CONSTITUTION: The fallen snow having been received in an acceptor 2 of a hollow cylinder provided with a heater 3 is thawn to become water drops which are then stored from a funnel 8 into a measuring tube 9. The water drops falling from this funnel 8 are detected with a photoelectric detector 6 and the snowfall is detected through counting by a counter connecting to the detector 6. On the other hand, the level of the water stored in the tube 9 is detected with a water level detecting part 12 and the supply and cutoff of power of the heater are controlled through a control part 15 according to the snowfall, whereby the detection of the snowfall corresponding to the snowfall condition is accomplished accurately with small power consumption.
