The quality of the air that we breathe, is very important to our health. This device analyses the air quality inside our homes, and records the values in a SD card. By analyzing the stored values, we know how the evolution of the parameters thru time was.
I will use temperature, humidity and air quality sensors that are cheap enough to use in this kind of project, without sacrificing too much the precision. The main idea behind this project is to know if the air is breathable or not.
