  • Interface Description

This module has an interface:4 PinPower supply and communication interfaces.

4 PinInterface2.54mmPitch bend pin, as shown in4.1Follows:

 

 

Are numbered from left to right1,2,3,4. They are defined as follows:

  • 1NumberPin: NextVCCPower (DC5V).
  • 2NumberPin: Connect the external circuitTrigEnd to this pin inputs a10uSHigh above, can trigger module ranging.
  • 3NumberPin: Connect the external circuitEchoSide, when the distance at the end of this pin outputs a high-level round-trip time of the width and ultrasound.
  • 4NumberPin: Connect the external circuit ground.
  • Ranging works

Modules ranging timing is shown5.1Follows:
