I've built a mobile airpollution sensor together with a few other parents and their kids at my 8-year old son's primary school in London. Air pollution is a big topic as the school is right next to a busy road, a lot of children are suffering from asthma and Islington has been pretty useless in collecting/publishing data. So we've started taking things in our own hands and built a handful of raspberry pi based monitors in class rooms, the playground and children take it with them on their school run. geo-tagged data is automatically uploaded to little influxdb/grafana based web service wheneve the pi has a wifi connection. Makes it an interesting project for kids to look and interpret charts and stuff as well. Currently we're measuring PM2.5/PM10, temp and humidity only, haven't had the time yet to look into NOx sensors yet...
