Overview

Sharp Optical Dust Sensor (GP2Y1010AU0F) is detecting very fine particles, such as cigarettes, which is particularly effective.

And it is a commonly used air purifier system.

In this device, an infrared light -emitting diode and photoelectric transistor tube are arranged to allow it to detect the dust reflex light in the air.

The sensor has extremely low current consumption (maximum 20mA, 11 mAh typical), and can be equipped with a sensor up to 7VDC.The output is an analog voltage proportional to the measured dust concentration, and the sensitivity is 0.5V/0.1mg/m3.

Detection principle

The principle is as shown in the figure below. There is a hole in the center of the sensor that allows the air to flow freely and transmit LED light at a directed. It is determined by detecting the light after the dust refraction in the air.Use test code:
int dustpin = 0;

Float dustval = 0;
int LEDPOWER = 2;
int Delaytime = 280;
int Delaytime2 = 40;
Float Offtime = 9680;
void setup () {
Serial.begin (9600);
pinmode (LEDPOWER, OUTPUT);
pinmode (dustpin, input);
}
void loop () {
// LEDPOWER IS Any Digital Pin on the Arduino Connect to Pin 3 on the Sensor
digitalWrite (LEDPOWER, LOW);
delaymicroseconds (delaytime);
dustval = Analogream (dustpin);
delaymicroseconds (delaytime2);
digitalWrite (LEDPOWER, HIGH);
delaymicroseconds (OFFTIME);
delay (1000);
if (dustVal>36.455)
Serial.println ((Float (Dustval/1024) -0.0356)*120000*0.035); Test the data and air quality comparison:
3000 + = very bad
1050-3000 = poor
300-1050 = Generally
150-300 = good
75-150 = Very good
0-75 = Very good Sensor Pin Arduino Pin
1 Vled –>5V (150ohm Resistor)
2 LED-GND –>GND
3 LED –>Digital Pin 2
4 S-GND –>GND
5 Vo –>Analog Pin 0
6 Vcc –>5V
The LED pin must be adjusted to a 1ms cycle.
The LED seems to use the PNP transistor to power on, and the LED pin must receive a lower voltage.
