Basic Working Principle:
(1) Using IO port TRIG measuring distance, high level for at least 10uS.
(2) Module automatically sends eight 40kHz , automatically detects whether there is return .
(3) When there is return , through IO port output a high level, the duration of the high level is the time of ultrasonic from sending to returning.Test distance = (high level time * sound velocity (340m/S))/2;
This module is simple to use, a port sends a high level of more than 10uS, then wait for high level output at receive port. Timer was enabled once there is output, and read time when this port becomes low level, which is the time of this measurement. Use the time to calculate distance. Constantly cycle measurement can your mobile measuring values.
Formula:
uS/58= cm or uS/148= inches;
Or:
Distance = high level time * sound velocity(340m/S)/2;
