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: 2.use IO port TRIG to trigger ranging. It needs 10 us high level signal at least 3.Module can send 8 pro 40 kz square wave automatically. And will test if there is any signal returned. 4.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*sound velocity(340m/s) 2 5.electric parameter Electric parameter HC-SR04 ultrasonic module Operating voltage DC 5V Operating current 15 mA Operating frequency 40 Hz Utmost range 4 m Nearest range 2cm Measure angel 15 ° Input trigger signal 10uS TTL pluse Output echo signal Output TTL level signal. Proportional to the range specification 45*20*15 mm The sequence diagram above indicates that you just need to supply one 10 uS pulse or above to trigger the signal. Inside the module, it will send 8 pro 40kHz round electric level with testing the returning wave. Once tested that there is returning wave signal, then it will output echo signal. The pulse width of the echo signal is in direct proportion to the testing distance. Therefore, the distance can be caculated according the duration from the sending signal to receiving signal.
