GP2Y1010AU0F PM2.5 Dust Sensor – Sharp Optical Smoke Detector | Compoden
Sharp GP2Y1010AU0F Optical Dust Sensor – PM2.5 Smoke Particle Detector
Sharp GP2Y1010AU0F is an optical dust sensor that detects fine particles such as smoke, pollen, and dust in the air. It emits an infrared beam and measures the reflected light, outputting an analog voltage proportional to particle concentration. This compact module integrates easily with microcontrollers, making it ideal for air quality monitoring, HVAC systems, and DIY pollution trackers.

Compatibility
This sensor outputs an analog signal in the 0–5 V range, so it works with any microcontroller that has an ADC accepting 5 V. Popular choices: Arduino Uno, Mega, Nano (5 V boards) directly; ESP32/ESP8266 (3.3 V logic) require level shifting on analog input, or use a voltage divider. Raspberry Pi needs an external ADC (e.g., MCP3008). The sensor’s V‑LED pin should be driven intermittently to prolong IR LED life, but can be tied to VCC for continuous operation.
Wiring Notes
Typical wiring: sensor pin 1 (GND) to ground, pin 2 (Vo) to Arduino A0, pin 3 (VCC) to 5V, pin 4 (V-LED) to 5V through a 150 Ω resistor, pin 5 (LED‑GND) to ground. For best accuracy, read Vo during the LED‑ON pulse (triggered by driving a digital pin to V‑LED).
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 GP2Y1010AU0F works directly with 5 V Arduino boards. Connect Vo to any analog pin and read the voltage. Many Arduino libraries are available for straightforward integration.
How do I calibrate the sensor for accurate PM2.5 readings?
The sensor outputs a voltage linearly related to dust density. Zero‑dust voltage is typically around 0.5 V. Use a reference instrument or clean environment to establish calibration points, then map the output to µg/m³.
Can I run the LED continuously?
Continuous 5 V on V‑LED will work but shortens the IR LED lifespan. The datasheet recommends a 10 ms pulse / 10 ms off cycle for long‑term use. Most libraries implement pulsing by connecting V‑LED to a digital pin.
