Working
The ultrasonic sensor actually consists of two parts: an emitter, which
produces a 40kHz sound wave; and a detector, which detects 40kHz sound waves
and sends an electrical signal back to the microcontroller. In order to determine the
distance to an object, it is necessary to implement a timing loop in your
microcontroller code to measure the length of time required for the sound wave
generated by the emitter to traverse the distance to the object.
(1) Adopt IO trigger through supplying at least 10us sequence of high level signal,
(2) The module automatically send eight 40khz square wave and automatically
detect whether receive the returning pulse signal,
(3) If there is signals returning, through outputting high level and the time of high
level continuing is the time of that from the ultrasonic transmitting to receiving.
Test distance = (high level time * sound velocity (340M/S) / 2.
