Gorillacell Module 044: Fine Dust Sensor
Table of Contents

The Fine Dust Sensor is an input device used to measure the air quality of the surrounding environment by detecting the concentration of dust and smoke particles in the air.
The Gorillacell ESP32 Development Kit includes one Fine Dust Sensor module driven by the Sharp GP2Y10 sensor. It operates based on an optical detection principle, using an infrared (IR) LED and a photodiode arranged to measure the amount of light reflected by airborne particles. The intensity of the reflected light corresponds to the dust concentration in the air.

PINOUT
It has 4 pins which are
- GND - for the ground pin,
- VCC - for the supply voltage,
- VO - for the analog signal representation of the Dust Sensor, and
- LED - for controlling the sampling of the Fine Dust Sensor.
A logic HIGH on LED pin initiates the sampling while a logic LOW should be driven after a definite time (about 40 microseconds).
