GP2Y1010AU0F Dust Sensor Working
The dust sensor works on the principle of light scattering. This sensor uses an IR emitter LED as a transmitter and a Photodiode as a receiver. This dust sensor includes an airflow path, so both the IR LED & Photodiode are arranged near the Airflow path in the sensor.
The air enters the dust sensor using an air inlet valve where a light source illuminates the dust particles & the scattered light is changed into a signal through a photodiode. So these signals are simply amplified through the amplifier circuit after that it is processed to obtain the particle concentration. The scattered light intensity mainly depends on the particles of dust. When the dust particles are more within the air, then the light intensity will be higher. The o/p voltage at the sensor’s VOUT pin changes based on the scattered light intensity.

float sigVolt = 0;
float dustLevel = 0;
outVo = analogRead(sensePin);
sigVolt = outVo * (3.3 / 1024);
dustLevel = 0.17 * sigVolt – 0.1;
