Dust particle detection project
The sensor near this paper senses the amount of dust that is in the air. Below you can scan the QR codes to see the graph of the data in the past three days. The other QR code brings you to a website that tabulates all the data points. The graph is hard to see because of all the crowded data points however if you look closely you can see a trend on when school hours are and when we have assemblies. Since new data gets collected every 5 minutes you can see the changes in real time.
