Connection Diagram
Pin Definition
- VCC: 6~12V@Max 2A
- GND: Ground
- Trig: Measurement trigger pin - Low level pulse over 50us triggers one distance measurement. Holding this pin LOW will repeats the measurement every 100ms.
- ECHO: Pulse signal output pin – 1us high level pulse equals 1mm in distance. If error occurs in detection, a 15000us high level pulse will be generated.
