Originally I have the AQI information from BeijingAir’s XML information page directed on to my own web page with the help from Sam Thurman through Javascript. However the Arduino cannot pick up the AQI because it is written in Javascript. With help from my professor, Joseph Saavedra now I have the AQI from Beijing Air’s XML page  directed to my AQI web page through this simple php code.

When you go my AQI web page, you will see a number displayed in the browser. It is the AQI number that Beijing Air published. Base on this number Hope for Blue will change color according to this chart:

Inclosure

Below is the specimen for the component of the enclosure of the product. I have laser-cutted two plexiglass for the front and the back of the inclosure and 5 rings of the shape of the cloud to stag up for the sides of the cloud.
