== Pilot project ==
We are working on a pilot project to build a crowdsourced [http://www3.epa.gov/pmdesignations/faq.htm#0 PM2.5] air pollution sensor network. PM2.5 air pollution is a growing problem that affects many parts of the world. Government around the world are asked to publish open data of PM2.5 index from their monitoring stations. However, government and companies can only set up so many stations. As a result, people can not obtain meaningful insights from the data. For instance, we will not be able to know when the air is bad in our neighborhood due to a nearby construction site as the government data tells us the city has a healthy number of PM2.5. We also will not know if our office has worse air quality compared to outside air or that the route and the time we choose to do our daily run is very bad for our health. We have access to numbers, but they are not meaningful as it does not link to our day to day life.
