Product details
detailed introduction
The principle of AR851 dual machine 60 meter ultrasonic rangefinder is to use the known propagation speed of ultrasonic waves in the air to measure the time it takes for sound waves to reflect back when encountering obstacles after transmission. Based on the time difference between transmission and reception, the actual distance from the transmission point to the obstacle is calculated.
