Basic working principle:
Use IO port TRIG to trigger ranging, giving a high level signal
of at least 10us;
The module automatically sends eight 40khz square waves to
automatically detect whether there is a signal return;
There is a signal return, 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;

Note:
The installation of electronic modules requires basic knowledge
and requires a certain electronic professional foundation and
hands-on ability. Please purchase carefully!
Manual measurement, with small error. Please check size in
detail before purchase.
Real colors may slightly differ from the pictures, as it depends
on specific monitor settings and light brightness.
