This novel idea will rely on mobile sensors to collect data in an evenly spread-out area, and is known as the OpenSense project which is by EPFL, a federally funded institute of technology located in Switzerland, and ETH Zurich, a science and technology university in Zurich, Switzerland. The whole point of this idea is to take advantage of existing public transportation vehicles in order to create an extensive network of mobile air quality data collection sites.
Basically, the benefits of the OpenSense project would be tremendous. Imagine an asthmatic person who is thinking of going out, but then decides to check with the OpenSense page that details just how the air quality is like in the area which he/she intends to travel to. Parents too, will be able to know just which area has lower ozone concentrations to bring their kids to during a nice summer day.
