The device created was made to measure particulate matter pollution. It was coded with arduino. It uses a PM sensor to detect pollution, and displays it on a LCD screen where one of three lights (green, yellow and red) lights up, depending on the quality of the air. It wraps around poles so the public can easily access it so they are aware whether the area that they are is clean or polluted. When being applied to my building project, I chose to include a green roof which reduces the air pollution in it's area and therefore directly cleaning the air.
