Introduction: How to Interface With Optical Dust Sensor
This tutorial is going to teach you basics on using Optical Dust Sensor.
Step 1: Introduction
Sharp's GP2Y1010AU0F is an optical air quality sensor, or may also known as optical dust sensor, is designed to sense dust particles. An infrared emitting diode and a phototransistor are diagonally arranged into this device, to allow it to detect the reflected light of dust in air. It is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems.
To interface with this sensor, you need to connect to its 6-pin, 1.5mm pitch connector by using mating connector.
- Low Current Consumption (MAX: 20mA)
- Typical Operating Voltage: 4.5V to 5.5V (MAX: 7V)
- The presence of dust can be detected by the photometry of only one pulse
- Enable to distinguish smoke from house dust
- Dimensions: 1.81 x 1.18 x 0.69'' (46.0 x 30.0 x 17.6mm)
Step 2: Pin Definition
Step 3: Sample Hardware Installation
Step 4: Sample Schematic
The above schematic is applicable to both Arduino Uno and Arduino Fio.
*For Arduino Uno, connect Pin Vo of GP2Y1010AU0F to Pin A5 of Arduino Uno. And also, Pin V-LED and Pin Vcc of GP2Y1010AU0F can be connected to either 5V or 3.3V of Arduino Uno.
Step 5: Sample Source Code
To get the result, please download the sample source code attached below and upload it into Arduino.
*Kindly download the datasheet of Optical Dust Sensor for your own reference and for understanding the coding written better.
Step 6: Ways to Open "Serial Monitor"
Step 7: Result (1)
The reading shown on Serial Monitor when the optical dust sensor is left in a room. The measurement of dust density obtained shows that the air only contains a low amount of dust.
Step 8: Result (2)
The reading shown on Serial Monitor when a pen is inserted into the dust detector area. The measurement of dust density obtained shows that there is a high amount of dust in the air.
Step 9: Video
This video shows how optical dust sensor works.

We have a be nice policy.
Please be positive and constructive.
I have replicated your project and uploaded it to Youtube, giving you all the credit by linking here and not publishing any code. Video: https://www.youtube.com/watch?v=UbS5MFFQ0Qw Is it ok?
Question: I have made this project thank you. May I copy your instructions and code to an USB drive where I keep all information regarding my Arduino sensors/modules/projects? It is hard to remember which website has which project so I like to save everything on a USB.
