At the secondary school stage, Arduino boards with ambient air quality sensors could be used and placed in different areas, not only in the school but also in other parts of the town that are subject to different levels of pollution. The data collected would be displayed as a dynamic color graph on an LCD screen located in the school hall. Students could program them using a block programming language, so that the colors projected on the dynamic graphs would be pleasant when low pollution levels are detected and more aggressive when levels rise.
It could also relate to art in a more obvious way by having artwork projected instead of colors that convey positive or negative emotions depending on the results. For example, Munch’s “The Scream”, or a horror movie billboard when the results are negative, and a landscape depicting nature when the results improve.
From the data obtained by the sensors, comparisons could be made between the different areas and the causes could be sought, for example by conducting digital surveys, in order to carry out awareness campaigns through the school’s social networks with initiatives to improve pollution.
Finally, it would be observed whether these awareness campaigns have changed the air quality of the environment and a web page could be created to show the whole process to the community.
