Pinout Configuration

The VCC pin is used to supply power to the sensor, and it typically requires 3.3V or 5V (refer to the datasheet for specific voltage requirements). The GND pin is the ground connection and must be connected to the ground of your ESP32.

The GP2Y1010AU0F pinout is as follows:

  • Pin 1 (V-LED): LED power supply (typically connected to 5V through a 150Ω resistor).
  • Pin 2 (LED-GND): LED ground.
  • Pin 3 (LED): LED control input (connect to a digital output pin on the microcontroller).
  • Pin 4 (S-GND): Signal ground.
  • Pin 5 (Vo): Analog voltage output proportional to dust density (connect to an analog input pin on the microcontroller).
  • Pin 6 (Vcc): Power supply (typically 5V).

Wiring with ESP32

To interface the GP2Y1010AU0F with a microcontroller like an Arduino or ESP32, connect the sensor's Vcc to the 5V power supply, LED-GND and S-GND to ground, Vo to an analog input pin (e.g., A0), and LED to a digital output pin (e.g., D9). Additionally, connect V-LED to 5V through a 150Ω resistor. This setup allows the microcontroller to control the sensor's LED and read the analog voltage output corresponding to dust density.
