Ultrasonic Module Distance Sensor DC 3.3-5.5V for Arduino UNO R3 Robot

Great Sensors for Arduino Project. Having Fun With Electronics and Programming!

Module Working Principle:

1. 50ms test cycle shorter than HC-SR04 sensor.
2. Finished ranging, If you find an object in front, Echo pin will be high level, and based on the different distance, it will take the different duration of high level.
3. So we can calculated the distance easily.The distance=((Duration of high level)*(Sonic:340m/s))/2

Wiring Instructions: 

VCC ---- DC 3.3V-5.5V

GND ---- Ground Wire

Trig ---- Control End
