The Snow Depth Sensor – Model 5428-00 is an ideal solution for remotely monitoring snow depth or water levels. The Snow Depth Sensor works by measuring the time required for an ultrasonic pulse to travel to/from a target surface. An integrated temperature probe with solar radiation shield, provides an air temperature measurement for properly compensating the distance measured by the Snow Depth Sensor. An embedded micro-controller in the Snow Depth Sensor calculates a temperature compensated distance and performs an error checking routine.
Both distance and air temperature measurement are output by the Snow Depth Sensor as a analog signal between 0 to 2.5 VDC or 0 to 5 VDC.
