The Sharp GP2Y1010AU0F is a compact optical dust sensor that uses an internal infrared LED and phototransistor arranged diagonally to detect fine particles in the air. The sensor outputs an analog voltage proportional to dust density, and its pulse pattern can distinguish between smoke and dust particles.
Ideal for air quality monitoring projects, air purifier systems, and environmental sensing applications. Includes a connection cable for easy integration.
Key Features
- Optical Particle Detection – IR LED and phototransistor detect fine dust and smoke particles
- Analog Output – Voltage proportional to measured dust density with 0.5 V per 0.1 mg/m³ sensitivity
- Low Power – 11 mA typical, 20 mA max current consumption
- Wide Operating Range – Functions from −10 °C to 65 °C
Specifications

Jargon buster
Plain-language definitions for the technical terms used above.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- phototransistor
- A light-sensitive transistor that changes its electrical output when light hits it. Compared with a modulated IR receiver, a simple phototransistor can be more affected by ambient light, so it may need extra filtering or careful setup.
