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.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Preparing the Components
Here are the modules I have chosen:
I also make a shell of acrylic and assembled with a few screws. It seems very simple, but enough.
Update: All product is here.
Step 2: Assembly Components
Now, Connect the sensor, display and other modules to Arduino.
First of all, we need to insert the base shield to Arduino board. Then, insert the sensor, ethanol sensor combustible gas sensor and other modules to the Base shield in the following order.
And then Assembing Lipo rider and battery to acrylic pannel.
Step 3: Programming
Now, we have to prepare procedure for it. In fact, these sensors are not so convenient to use. Fortunately, Seeed have provided a library file for us. It costs me 1 more hour to complete this programming. Therefore, if you don’t want to code it, you can download here( Github.). But, please remember to choose the COM port and board.
When you get the code, you will have a file named Air_monitor.ino. Opening it with Arudino IDE (if you haven't, you should donwload it).
After downloading, you can run this device normally. Certainly, if you think it’s inconvenient to connect it with a USB cable, you can instead of it with a battery or even power it with a charger.
Step 4: Packaging Into Box
Alright, let’s make a device together.
Put them into a box that you like. Of course, you can also make one by yourself. But, if you think it’s a troublesome to make by yourself or you haven’t found the suitable material, you can use any box that you like. It’s all up to you. Definitely, a paper box is ok.
I also use a Lipo Rider to provide power for Arduino.
Step 5: Test It
Now, all components is into Skeleton box, turn on the Lipo Rider.The OLED Display should show message about air quality.
I put it on my desk. Isn’t it very cool? Want to see if it can work normally? It turned out to be true. Yes, it is.
