Ultrasonic Range Sensors

An ultrasonic range sensor uses sonar to measure the distance to an object. It consists of two ultrasonic transmitters, a receiver, and a control circuit. The transmitter emits high-frequency ultrasonic waves that bounce off any nearby solid objects, and the receiver listens for any returning echo. The echo is then processed by the control circuit to calculate the time difference between the transmitted and received signal. This time, along with some clever math, can then be used to calculate the distance between the sensor and the reflecting object. Datavision ultrasonic range sensors provide precise distance measurements on any surface and in any environment.
