Analogue, Digital and Active Approaches to Air Quality (2013)
These talks were given on 8 May 2013 at the Hub Westminster, London (http://westminster.the-hub.net/).
Part 1 : Analogue technologies
Andrew Wood,, Network for Clean Air introduces analogue technologies for measuring air quality, in particular gas diffusion tubes for nitrogen dioxide air pollution. These are an established technology used by many local authorities in the UK.

Part 2 : Digital technologies
This talk is about the Air Quality Egg project which is a digital monitor for air quality which is internet enabled. It's sold as a kit and itrelies on a community of software and hardware hackers/enthusiasts for its development. Jason Neylon - a AQE owner, and other members of the audience engage in the discussion and presentation by Andrew Wood, Network for Clean Air.

Part 3 : Active approaches
Jonathan Callaway from the Putney Society (http://www.putneysociety.org.uk/) in south west London, describes their air pollution campaign and the use of air monitoring in a 'citizen science' project. The Putney Society measured air quality using nitrogen dioxide (NO2) gas diffusion tubes and produced a map showing air pollution in and around Putney High Street. Their year long campaign persuaded Wandsworth borough council to respond which eventually lead to lower emission buses being introduced.
