Basic working principle:

• (1) Use IO port TRIG to trigger distance measurement 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) When there is a signal return, a high level is output through the IO port ECHO, and the duration of the high level is the time from the ultrasonic wave to the return. Test distance = (high level time * speed of sound (340M/S))/2;
