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, the duration of the high level is the time from the transmission to the return of the supersonic wave. Test distance = (high level 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. When there is an output, the timer can be turned on. When the port becomes low, the value of the timer can be read. The time at this time is the time of the ranging, and the distance can be calculated. With such continuous cycle measurement, you can reach the value of your movement measurement.
