Dust Sensor

A Dust Sensor is used to measure the concentration of dust particles in the air. Most commonly, hobby and DIY projects use optical dust sensors like GP2Y1010AU0F, which detect suspended particles by measuring light reflected from them.

It is widely used in air quality monitoring systems, pollution detection, and smart home automation projects.

🔹 How It Works

• An internal infrared LED emits light.

• Dust particles in the air reflect the light.

• A photodiode detects the reflected light.

• The module outputs an analog voltage proportional to dust concentration.

🔹 Key Features

• Detects fine dust particles

• Analog output

• Real-time air quality monitoring

• Compact and easy to integrate

• Suitable for indoor monitoring systems

  🔹 Typical Specifications (GP2Y1010 Type)

  • Operating Voltage: 5V

  • Output Type: Analog

  • Detectable Particle Size: ≥ 0.8µm

  • Low power consumption
