Measuring air quality with children

Using small sensors, we were able to measure a whole week of the children's everyday school life with them. The spatiotemporal data analysis is still in progress, but we can see what the results look like for the participants and their parents. The graph shows that some activities increased the overall workload while others didn´t. This can be individually discussed with each participant to see which activities they could reduce or modify. For instance, this graph shows that indoor air is less polluted than outdoor air for most of the week, but this may only sometimes be the case if there are sources of pollution in the home, such as boilers, frequent frying, or even smoking.

According to the map, we successfully covered a significant portion of Brno with the help of our children, generating several thousand records.

Upon analysing the data, we noticed variations in pollutant concentrations during children's trips to and from school across different locations. It's essential to consider the timing of measurements at each school. Notably, the schools with the highest pollutant levels were all assessed in February, coinciding with the coldest temperatures in Brno this year.
