What is it the bAIR system?

Measuring and Mapping of Air Quality by Bike - A PITLab project: 

a clip-on for bicycles that measures different kinds of gas (e.g. carbon dioxide, ozone, nitrogen dioxide, particulate matter) 
as well as temperature and humidity, and potentially many other environmental and urban properties.
The sensors in the clip-on send info to your Android phone, and information from both your phone (time and location) 
and the sensors are sent to our database. 
The gathered information can then be shown on a map e.g. Google Maps or OpenStreetMap.

The bAIR system is based on earlier projects at ITU, like http://noxdroid.org (2011)
and the great work done over at http://aircasting.org
