Pinout
4Low source legibility.The original manufacturer datasheet for this part was difficult to read, so this pinout may be incomplete or imperfect. Always confirm against the specific manufacturer’s datasheet before wiring.
| Pin | Name | Functions | Notes |
|---|---|---|---|
| Vcc | power | POWER | 5V power for best results |
| Trig | trigger | GPIO | 3V or 5V, initiates ultrasonic burst |
| Echo | echo | GPIO | 5V logic level, goes high when ultrasonic burst is transmitted and stays until echo received |
| Gnd | ground | GND | Ground pin |
