A while back, I wrote a post about testing an earlier version of the Pollution Guardian prototype<\/a> in the University of Surrey\u2019s Envilution\u00ae laboratory test chamber.<\/p>\n

A key point of using the chamber was to be able to objectively assess<\/strong> how well individual particulate matter and gas sensors performed, compared to high quality laboratory measuring equipment, in the controlled conditions of the lab test chamber.<\/p>\n

Any issues found with sensors in the lab, are likely to be more significant in real world testing. In fact, the Envilution\u00ae chamber has helped us triage some significant issues with gas sensors over the course of the project.<\/p>\n

The collaboration with the University has extended beyond the lab into the on-road field testing activities. On multiple occasions we have tested a car loaded up with Pollution Guardian prototypes and high grade laboratory test instruments. This was in order to compare the performance<\/span> of <\/span>prototypes in real life conditions i.e. with rapidly changing levels of air pollutants combined with environment changes to the car interior via the action of the car air conditioning system.<\/span><\/p>\n

In the video below, Professor Prashant Kumar, Founding Director of the University of Surrey\u2019s Global Centre for Clean Air Research (GCARE)<\/a> summarises the status of the Pollution Guardian work and his team member, Dr. Hamid Omidvarborna, tells us about the Envilution\u00ae test chamber.<\/p>\n
