Ultrasonic Ranging Module HC - SR04
Product features:
Ultrasonic ranging module HC - SR04 provides 2cm - 400cm non-contact
measurement function, the ranging accuracy can reach to 3mm. The modules
includes ultrasonic transmitters, receiver and control circuit. The basic principle
of work:
(1) Using IO trigger for at least 10us high level signal,
(2) The Module automatically sends eight 40 kHz and detect whether there is a
pulse signal back.
(3) IF the signal back, through high level , time of high output IO duration is
the time from sending ultrasonic to returning.
Test distance = (high level time×velocity of sound (340M/S) / 2,

Attention:
The module is not suggested to connect directly to electric, if connected
electric, the GND terminal should be connected the module first, otherwise,
it will affect the normal work of the module.
When tested objects, the range of area is not less than 0.5 square meters
and the plane requests as smooth as possible, otherwise ,it will affect the
results of measuring.
