Is DIY a device that can monitor the environmental quality condition at any time a problem for you? Actually, it’s not a tough job. Here, on the desk, is a DIY device which can help me get the informant about the air pollution in the room.

This device can detect the concentration of dust, gas, alcohol and other organic gas in the room. In order to make this process faster and simpler, I choose to use Seeedstudio’s Grove modules.

In addition, its whole shell is made of acrylic and assembled with a few screws. You see, it’s all made by myself.

Step 1: Preparing the Components

Here are the modules I have chosen:

1.Seeeduino
2.Base Shield
3.Grove - Dust Sensor
4.Grove - Gas Sensor(MQ9)
5.Grove – HCHO Sensor
6.Lipo Rider pro and Battery
7.Grove – OLED Display 128*64

I also make a shell of acrylic and assembled with a few screws. It seems very simple, but enough.

Update: All product is here.

<p>I couldn't find the code you used for the Arduino. The link for downloading the files (http://seeed-studio.github.io/Air_Quality_Test_Box/) isn't working. Could you please provide the code?</p>
<p>Does anyone have any information on calibrating these sensors. The pots on the sensors are there for a reason. Otherwise the numbers are meaningless and can only be used to compare figures (like my room has more dust than the other room).</p>
<p>How did you calibrate the sensor in order to get &mu;g/m^3??</p><p>In the manual the only thing that can help you calibrate it, is the chart of ciggarete smoke and it is in pieces/280ml of air. Not in &mu;g. How did you convert the units to mass? How do you know that 1 particle of PM1 or 2.5 can be related to mass? PM is diameter and not mass. Please if you have info on this I really need it. </p>
This dust sensor can detect regional haze? Or can be detected in PM2.5 and PM10?
what size box did you use? where did you get it?
I get it here http://www.seeedstudio.com/depot/skeleton-box-p-1407.html?cPath=55_60
thanks. i missed it for sure on the site.
you product links are missing the &quot;:&quot; in http:// and so dont' work. <br> <br>also, neat sensors, but any idea what the values mean? I mean, how much dust is a level that action should be taken?
Dust sensor just get the pm2.5, https://en.wikipedia.org/wiki/Particulates
