The 260-705 Ultrasonic Snow Depth Sensor is a low cost, rugged sensor for reliable snow depth measurement. The 260-705 is a non-contact object detecting and ranging sensor that uses high frequency sound to detect and localize objects in a variety of environments. Ultrasonic sensors measure the time of flight for sound that has been transmitted to and reflected back from nearby objects within a defined area. Based upon the time of flight, the sensor outputs a range reading. Temperature compensation is applied to every reading using an integrated temperature sensor. Multiple sensor readings are analyzed using algorithms optimized for snow measurement, ensuring accurate results. The 260-705 can interface with most data loggers.
