This module size: 45mm*20mm*1.6mm.Plate two with a radius of 1mm mechanical hole,
From left to right: 1,2,3,4.They are defined as follows:
1 Pin: VCC power (DC 5V).
2 Pin: external circuit Trig terminal, to this pin input a 10uS above high level, can trigger module location.
3 Pin: external circuit Echo terminal, when the distance at the end, this pin will output a high level, level width for the ultrasonic travel time of the sum
4 Pin: to external circuit GND
