260-700 Ultrasonic Snow Depth Sensor

260-700 Ultrasonic Snow Depth Sensor
260-700 Ultrasonic Snow Depth Sensor
The 260-700 Ultrasonic Snow Depth Sensor is an inexpensive 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.
Product Details

The 260-700 Ultrasonic Snow Depth Sensor is an inexpensive 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 can also be output digitally as serial ASCII. Specify analog or digital output at time of order.

Due to the simplified interface, the depth sensor can interface with any data logger or control system that can delay at least 3 seconds after powering up before measuring the output.
