The document presents air quality data from a sensor located at a school over a period of time. It records the weather conditions and measurements of particulate matter (PM2.5) at different dates and times. The conclusion is that as winter approaches, lower temperatures require more home heating which produces smog and causes the air quality measured by PM2.5 levels to gradually deteriorate.

2. Before we
start…
In the presentation I will present
you how air pollution changes over
time.
For the sake of our research, I used
a sensor located at our school.

9. CONCLUSION
A simple conclusion can be drawn from the research-
when winter is coming and lower temperatures are becoming more
typical every day - that forces us to heat our houses, and that produces
smog. As a result, the condition of the air is deteriorating.
