Fundamental Principles

A short ultrasonic pulse is transmitted at the time 0, reflected by an object. The sensor receives this signal and converts it to an electric signal. The next pulse can be transmitted when the echo fades. This time period is called cycle period. The recommend cycle period should be no less than 50ms. If a 10us width trigger pulse is sent to the signal pin, the ultrasonic module will output eight 40kHz ultrasonic signals and detect the echo back. The measured distance is proportional to the echo pulse width and can be calculated by the formula above. If no obstacle is detected, the output pin will give a 38ms high level signal.
