Key:
Dark Blue = committed schools collecting ozone and PM 2.5
Light Blue = committed schools or sites collecting ozone or PM 2.5
It collects data continuously and pushes the data to a server via wifi. Students can view their sensor on the Purple Air map, compare their sensor to other sensors, download, graph and analyze fine particulate data. Data is archived for convenient access during the busy school year. The sensor is weather resistant. You should visit it occasionally though to make sure spiders and other critters (including students) do not interfere with the laser particle counters.

It is an indoor, handheld gas sensor. We used it outdoors and sheltered it from rain and snow. I recommend keeping it outdoors for three weeks to collect a larger range of data to represent that season sample. Make sure your ozone and PM sensors are sited away from HVAC or a space that prevents freely moving air. This sensor does not display data on a map. However, Aeroqual sells sensors that do populate a map.
This was the OAYF project's timeline and tasks. With the help of teachers and partner organizations, I raised $15,000 to support OAYF. The funds purchased ozone sensors ($1300 each) and particulate sensors ($300 each). Remaining funds were dedicated to project incidentals and the Student Environmental Action Showcase on Earth Day 2020. For more information about SEAS, see the link below.
