PM2.5 GP2Y1010AU0F Dust Smoke Particle Sensor + Cable capacitor resistor

The GP2Y1010AU0F Dust Smoke Particle Sensor is an optical air quality sensor that detects fine dust and smoke particles. An infrared LED and a phototransistor are placed at an angle inside the housing, so light scattered by particles in the air hole is turned into an analog voltage proportional to dust density. It is widely used in PM2.5 and air purifier projects, and it comes with a cable plus the resistor and capacitor for its LED drive circuit.

GP2Y1010AU0F Dust Smoke Particle Sensor Applications

• Air purifiers and air conditioners
• Indoor air quality and dust monitors
• Smoke detection experiments
• Arduino and ESP32 environment stations

What's in the Box

• 1 × GP2Y1010AU0F dust sensor
• 1 × connection cable
• 1 × resistor and 1 × capacitor for the LED circuit

Tip: Wire the included resistor and capacitor into the LED circuit shown in the datasheet, which uses 150 Ω in series from 5 V and 220 µF to ground at the LED supply pin. Pulse the LED pin for 0.32 ms every 10 ms, read the output about 0.28 ms after the pulse starts, and average several readings for a steady value.
