The Judd Communications Depth Sensor is an inexpensive solution for remotely measuring snow depth or water levels.

It connects easily to all HOBO U30 Weather Stations and receives its power supply through them. It provides an analog signal for the VIA module of the U30.

The sensor measures the distance from the sensor to a target. The sensor works by
measuring the time required for an ultrasonic pulse to travel to and from a target surface. An integrated temperature probe with solar radiation shield, provides an air temperature measurement for properly compensating the distance measured. An embedded microcontroller calculates a temperature compensated distance and performs error checking.

Both distance and air temperature can be output as an analog signal between 0 to 2.5 Volts or 0 to 5 Volts.
The depth sensor is user configurable by means of internal dip switches. Several configurations are possible and allow the depth sensor to work with as many different type of systems as possible.

Accurate measurement of snow depth poses many difficult problems. The Judd Communications Depth Sensor has proven very effective in measuring snow depth, which makes it well suited for other various applications.
