BBC Article: “Kenya pollution: How air sensors are helping people fight pollution”

The subject of the BBC News article, John Keiti, lives in a part of Kenya that suffers from serious pollution. He borrowed air pollution sensors and set up a system that broadcast the data. As a result a local factory has had to improve it’s filtering system leading to cleaner air.

Initially there may have been more doubts about the reliability of Keiti’s data but as more information is collaborated by others there would be more confidence in his results. Consider why some groups might have their own reasons for viewing Keiti’s work with less confidence.
