Description:
Sharp’s GP2Y1010AU0F is an optical air quality sensor, 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.
The sensor has a very low current consumption (20mA max, 11mA typical), and can be
powered with up to 7VDC. The output of the sensor is an analog voltage proportional
to the measured dust density, with a sensitivity of 0.5V/0.1mg/m3.
To interface with the sensor you need to connect to its 6-pin, 1.5mm pitch connector.
Specification
Compact, thin package (46.0 × 30.0 × 17.6 mm)
Low consumption current (Icc: MAX. 20 mA)
The presence of dust can be detected by the photometry of only one pulse
Enable to distinguish smoke from house dust
Lead-free and RoHS directive compliant
Include:
• 1 x Dust Sensor
• 6 x Dupont Line
• 1 x Resistor
• 1× Capacitor

Tutorial
In this exercise with the use of our Arduino Yún, we learn to build our detector air
quality. To do this we will use the capabilities of the GP2Y1010AU0F. It's a dust sensor
by optical sensing system with an infrared emitting diode (IRED) and a phototransistor
that are diagonally arranged into this device. It detects the reflected light of dust in air.
Especially, it is effective to detect very fine particle like the cigarette smoke. The output
of the sensor is an analog voltage proportional to the measured dust density, with a
sensitivity of 0.5V/0.1mg/m3.
What do we need
an Arduino Yún board
a Sharp Optical Dust Sensor (GP2Y1010AU0F)
a breadboard
a 220 uF capacitor
a 150 Ohm resistor
a bunch of wires

Be sure to follow the connections shown in the fritzing circuit and in the next table :
Sharp pin 1 (V-LED) => 5V (connected to 150ohm resistor,220 uF capacitor)
Sharp pin 2 (LED-GND) => Arduino GND pin
Sharp pin 3 (LED) => Arduino pin 2
Sharp pin 4 (S-GND) => Arduino GND pin
Sharp pin 5 (Vo) => Arduino A0 pin
Sharp pin 6 (Vcc) => 5V
