The Optical Dust Sensor Module is a sensor used for detecting dust particles and air quality levels in the environment. It is commonly used in air pollution monitoring and purification systems.
The Optical Dust Sensor works using an infrared LED and photodiode to detect dust particles suspended in air. When particles pass through the sensing chamber, light is scattered and measured by the sensor to estimate dust concentration.
These sensors are widely used in:
Air quality monitoring
Air purifiers
Smart environment systems
Pollution detection projects
Popular versions include sensors like:
Sharp GP2Y1010AU0F
DSM501A
PM2.5 laser-based sensors
The sensor outputs either:
Analog voltage
PWM signal
UART digital data (depends on model)
