Gasser Pollutant Detector #piday #raspberrypi @Raspberry_Pi

Gasser

Raspberry Pi-based sensor package for detecting air pollution in Paris, the Gasser project at LaboCitoyen:

Gasser is a self-contained mobile sensor for sensing NO2, O3, and SO2. Currently we run it only with NO2 as that is the most present pollutant in Paris.

Gasser has essentially three main parts:

  • The sensor (any analog or digital sensor can work) — top left in the main box.
  • The ADC & computer (analog to digital converter) — main board inside the box.
  • The communication medium (3G, ethernet, or write to an SD card) — white dongle on the left side of the image.
  • Power — black box on the left side of the image.
