Product feature
:
HC-SR04 ultrasonic module can offer non-contact distance sensing function, the range of which is 2cm?400cm., and the range accuracy is up to 2mm; the module includes ultrasonic transmitter, receiver and control circuit.
The basic operation principle is below:
(1)Use IO port TRIG to trigger ranging. It needs 10 us high level signal at least
(2)Module can send 8 pro 40 kz square wave automatically, and will test if there is any signal returned.
(3)If there is signal returned, output one high level signal via IO port ECHO. The duration of the high level signal is the time from transmitter to receiving with the ultrasonic.
Testing distance =duration of high level*voice velocity(340m/s) / 2
Physical map:
Refer to the wiring diagram below,
VCC supply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output.

Note:
1
. for this module, keep in mind not to connect with electricity. If it is connected with electricity, you need to connect up
the GND port of the module firstly, otherwise it will affect the normal working of the module.
2. When testing, the coverage of the tested object is 0.5 square meter or below, and try to make the plate smoothly.,
otherwise, it will affect the result of the testing.
