Shameless plug: I wanted to measure PM10 and PM2.5 pollution level in my neighbourhood, so I built the ESP8266-based sensor using instructions from Luftdaten [1] and since the original interface is pretty ugly, I created my own UI: http://smog.rekawek.eu/ http://smog.rekawek.eu/ https://github.com/trekawek/air-quality-info https://github.com/trekawek/air-quality-info (I know, it's PHP, but can be hosted virtually anywhere!)
