Wiring mode, VCC, trig (control terminal), echo (receiving terminal), GND

How to use this product:

A control port sends a high level above 10US, and you can wait for a high level output at the receiving port. Once there is an output, you can start the timer to count. When this port becomes low, you can read the timer value. Time is the time of this range measurement to calculate the distance. Such continuous periodic measurement can reach the value of your mobile measurement~~

The working principle of the module:

(1) Use IO to trigger the ranging and give a high level signal of at least 10us;

(2) The module automatically sends 8 40khz square waves and automatically detects whether there is a signal return;

(3) There is a signal return, a high level is output through IO, and the duration of the high level is

The time from emission to return of ultrasound. Test distance = (high level time * speed of sound (340M/S))/2;
