Basic Working Principle:
(1) Using IO port TRIG trigger measuring distance, high signal for at least 10uS.
(2) Module automatically sends eight 40kHz square wave, automatically detects whether there is return signal.
(3) When there is return signal, through IO port ECHO output a high , the duration of the high is the time of ultrasonic wave from sending to returning.Test distance = (high time * sound (340m/S))/2;
This module is simple to use, a port sends a high of more than 10uS, then wait for high output at receive port. Timer was enabled once there is output, and read time when this port becomes low , which is the time of this measurement. Use the time to calculate
