Dust Sensor

The Dust Sensor Module is a compact and reliable air quality sensor designed to detect airborne particulate matter (PM) such as dust, smoke, and pollen. Using an infrared LED and photodetector, the sensor measures changes in light intensity caused by dust particles in the air, making it ideal for air purifiers, air quality monitoring systems, HVAC units, and environmental sensing projects. It provides an analog output that can be read by Arduino, ESP32, Raspberry Pi, and other microcontrollers. Commonly used in indoor air quality systems, the dust sensor helps monitor pollution levels and maintain healthy environments.
