Model 260 Ultrasonic Snow & Water Depth Sensor

The Model 260 Ultrasonic Snow Depth Sensor is a cost effective solution for remotely measuring snow depth or water levels. 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 an error checking routine.

Both distance and air temperature are output as an analog signal between 0 to 2.5 volts or 0 to 5 volts. Measurements are also output digitally as serial ASCII. Due to the simplified interface, the depth sensor can interface with any data acquisition system or datalogger, such as the Neon and Starlog Data Loggers, which can delay at least 2 seconds after powering up before measuring the output.
