Description: Ultrasonic sensor working principle:
(1) trigger the ranging with I/O to give at least 10us high level signal.
Module automatically sends 8 40kHZ Fang Bo to automatically detect whether there is a signal return.
(3) a signal is returned, and a high level is output through I/O. The duration of high level is the time from ultrasonic emission to return.
Test distance = (high level time * sound speed (340M/S)) /2.
