The Sharp Optical Dust Sensor (GP2Y1010AU0F) is |
|
especially effective in detecting very fine particles |
|
like cigarette smoke, and is commonly used in air |
|
purifier systems. 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. |
|
In previous videos I have shown you the Air quality |
|
monitors based on DSM501A and PPD42NS sensor boards. This |
|
time I will present you same device , now based on Sharp |
|
GP2Y1010AU0F sensor board which is also very cheap and |
|
costs around $ 5. The electrical scheme of this device is |
|
very simple and is shown in the figure below.The air |
|
sensor has a very low current consumption (20mA max, 11mA |
|
typical), and can be powered directly from Arduino board. |
|
The output of the sensor is an analog voltage |
|
proportional to the measured dust density, with a |
|
sensitivity of 0.5V/0.1mg/m3. |
|
I modified the Arduino sample code from "Dfrobot" page so |
|
reading the values is in microg/m3. Next I wrote a |
|
Processing code based on "meter" library, so that these |
|
values are represented on the PC monitor in the form of a |
|
large analogue instrument, giving it a distinct visual |
|
effect . |
|
|
|
Lastly let's compare all three sensor boards(DSM501A and |
|
PPD42NS which I have described in previous videos and |
|
Sharp GP2Y1010AU0F described above).All three sensors are |
|
very cheap and can be purchased for a few dollars. |
|
According to the results I got testing them under the |
|
same conditions and the winner is Sharp GP2Y1010AU0F. |
|
There are a number of positive points among which: |
|
|
|
-It is more sensitive to very low values |
|
-It has very low power consumption and can be powered |
|
directly from the Arduino |
|
-Very simple Arduino code that is easily customizable |
|
-It has an analog output so it can be directly connected |
|
to a measuring instrument without any additional |
|
electronics |
