Figure Pin 4.1:4 interface

From left to right order number 1,2,3,4. they are defined as follows:

1 Pin: VCC power supply (DC 5V).

2 Pin: the external circuit of the Trig terminal, the pin input to a 10uS above the high level, can trigger module ranging.

3 Pin: the Echo terminal of the external circuit, when the distance is over, the pin will output a high level, the level of the ultrasonic wave and the sum of the sum.

4 Pin: the ground of the external circuit.
