GP2Y1010AU Compact Optical Dust Sensor

GP2Y1014AU Compact Optical Dust Sensor – Analog Airborne Particle Detection Sensor
The GP2Y1014AU optical dust sensor is a compact and reliable sensor module for detecting airborne dust and fine particles such as smoke, pollen, or other microscopic particulates. It produces an analog voltage output proportional to dust concentration, making it ideal for air quality monitoring, embedded systems, and Arduino or microcontroller projects.

Key Features:

• Optical detection principle: An integrated infrared LED and phototransistor detect reflected light from particles in air.

• Operating Voltage: 5 – 7 V DC, widely compatible with development boards.

• Low Power Consumption: ~11 mA typical (max ~20 mA).

• Particle Sizing: Detects particles from around 0.8 µm diameter, suitable for fine dust measurement.

• Analog Output: 0 – 3.7 V analog signal proportional to dust density (mg/m³).

• Wide Operating Range: Works from -10 °C to +65 °C, with storage range to -20 °C to +80 °C.

• Compact Size: Approx 46 × 33 × 18 mm — easy for integration and enclosure mounting.

• Included Accessories: Often comes with a 6-pin cable, resistor and capacitor for optimized signal measurement when offered as a module.

Typical Applications:
✔️ Air quality monitors, indoor AQI measurement systems.
✔️ Arduino, ESP32, Raspberry Pi sensor integrations.
✔️ Air purifiers and HVAC systems with automatic control.
✔️ Educational and environmental projects that require real-time dust data.
