Mode of connection:
1.VCC 2.trig(T) 3.echo(R) 4.GND
Use method: Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not.
The out pin of this module is used as a switching output.
When anti-theft module, and without the feet when ranging modules.
HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal
The hc-sr04 arduino ultrasonic sensor can send eight 40 kHz and detect whether there is any pulse signal back.If it back, a high level signal will be outputed by IO, and the duration of the signal is the time from sending ultrasonic to returning
