Sharp GP2Y1010AU0F PM2.5 Dust Sensor - Optical Smoke Detector
Sharp GP2Y1010AU0F Optical Dust Sensor PM2.5 Smoke Particle Sensor
The Sharp GP2Y1010AU0F is an optical dust sensor designed to detect airborne particles such as smoke, pollen, and PM2.5. It outputs an analog voltage proportional to dust density, making it ideal for air quality monitoring systems, smart home appliances, and industrial environmental sensing. Its compact design and low power consumption allow easy integration with microcontrollers like Arduino, ESP32, and Raspberry Pi.

Compatibility
This sensor operates at 5V and outputs an analog signal, compatible with any microcontroller with an ADC pin, including Arduino Uno, Nano, Mega, ESP32, and Raspberry Pi (with external ADC). It is commonly paired with 3.3V systems using a voltage divider on the analog output.
Wiring Notes
Connect VCC to 5V, GND to common ground, and Vo to an analog input. For the IR LED drive, connect the LED pin through a 150Ω resistor to 5V, and use a 220µF capacitor between LED and ground for stable operation. Ensure no obstructions in the sensing aperture.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, the Sharp GP2Y1010AU0F works with 5V Arduino boards like Uno and Mega. Connect analog output to any ADC pin and use a 150Ω resistor and 220µF capacitor on the LED drive circuit as per datasheet.
How accurate is the PM2.5 detection?
The sensor provides an analog voltage proportional to dust density. It can detect particles down to 0.5µm, with a typical sensitivity of 0.5V per 0.1mg/m³. Use a calibration curve for precise measurements.
Does it require calibration?
Factory calibration provides a baseline, but for accurate readings, calibrate using known dust conditions. The output voltage varies with supply voltage, so use a stable 5V supply.
