4. Traffic control;
5. Security and industrial control;
6, artificial intelligence, teaching and research

Basic working principle:
(1) Using IO port TRIG to trigger ranging, giving a high level signal of at least 10us;
(2) The module automatically sends eight 40khz square waves to automatically detect whether there is a signal return;
(3) There is a signal return, and a high level is output through the IO port ECHO, and the high level duration is the time from the transmission to the return of the ultrasonic wave. Test distance = (high time * sound speed (340M / S)) / 2;

This module is easy to use. A control port sends a high level above 10US, so you can wait for the high level output at the receiving port. You can turn on the timer when there is an output. When this port goes low, you can read it. The value of the timer, at this time is the time of the distance measurement, in order to calculate the distance. Such continuous cycle measurement, that is, you can reach the value of your mobile measurement.
