The AR831+ultrasonic rangefinder uses the known propagation speed of ultrasonic waves in air to measure the time it takes for sound waves to reflect back from obstacles after being emitted. Based on the time difference between emission and reception, the actual distance from the emission point to the obstacle is calculated.
