GP2Y1010AU0F Overview

The Sharp GP2Y1010AU0F is a compact optical dust sensor designed to detect fine airborne particles such as dust and smoke. It is widely used in air quality monitoring systems due to its simple structure, stable performance, and low power consumption. The sensor provides an analog voltage output that increases as the concentration of dust particles in the air rises, making it easy to interface with microcontrollers like Arduino or ESP32.

This sensor works using an infrared LED and a phototransistor arranged diagonally inside a small sensing chamber. When airborne particles pass through the chamber, they scatter the infrared light. The scattered light is detected by the phototransistor and converted into an electrical signal proportional to dust density. Because of this optical light-scattering method, the GP2Y1010AU0F is effective at detecting very fine particles commonly found in indoor environments.

GP2Y1010AU0F Features

Optical Dust Detection Technology

The GP2Y1010AU0F uses infrared light-scattering technology to detect airborne dust particles. When dust passes through the sensing chamber, it scatters IR light toward a photodiode, allowing the sensor to estimate particle concentration accurately.

High Sensitivity to Fine Particles (≥ 0.5 µm)

This sensor can detect very fine particles such as cigarette smoke and household dust. Its ability to sense particles as small as 0.5 µm makes it suitable for indoor air-quality monitoring applications.

Analog Voltage Output

The sensor provides a linear analog output voltage proportional to dust density. This makes it easy to interface with microcontrollers like Arduino or ESP32 without complex digital communication protocols.

Low Power Consumption

With a maximum current consumption of around 20 mA, the GP2Y1010AU0F is efficient for continuous monitoring systems and portable devices where power usage must be minimized.

Fast Response Time

The sensor responds in less than one second, allowing near real-time detection of changes in dust concentration. This is useful for applications requiring quick air-quality feedback.

Smoke and Dust Differentiation Capability

Due to its optical response characteristics, the sensor can help distinguish fine smoke particles from larger household dust, improving detection accuracy in indoor environments.

Compact and RoHS-Compliant Design

Its compact form factor allows easy integration into small enclosures, while lead-free and RoHS compliance ensures environmental safety and regulatory compatibility.
