Sense Your city
As a child I suffered from asthma. Any person who has gone through similar experience becomes acutely aware of the importance of the quality of the air we are breathe. As I was looking for data related hackathons I came across this awesome dataset by DataCanvas. The dataset contains measurements such as temperature and dust level, collected by citizen's DIY sensors. Sense your city is a pretty exciting project put together by Data Canvas. I live in bay area now, so I got curious and started exploring the data from sensors located in San Francisco. Code is in github.
