GP2Y1010AU0F Optical Dust Sensor

The GP2Y1010AU0F Optical Dust Sensor detects airborne particulate matter by measuring light scattering. An infrared LED and photodetector detect particles in the air stream for air quality monitoring applications.

Key Features

• Optical dust detection
• Infrared LED + photodetector
• Analog output
• Detects PM2.5 and larger particles
• Compact size
• Low power
• Internal airflow design

Technical Specifications

Applications

• Air quality monitoring
• PM2.5 detection
• Indoor air quality
• Environmental sensing
• Air purifier feedback

Important Notes

• Requires pulsed LED operation – not continuous
• Use SharpDustSensor library for Arduino
• Calibrate against known reference
• Sensitive to orientation – mount as specified
• Keep sensing chamber clean for accuracy
• Not as accurate as laser-based sensors (PMS5003)
