MIT researchers have developed an open-source mobile pollution detector called Flatburn, allowing individuals to monitor local air quality affordably and readily. Air pollution is a significant public health concern, with over 4 million premature deaths worldwide attributed to it each year, largely due to the lack of comprehensive air quality measurements. Flatburn can be assembled using inexpensive parts or 3D printing and has been tested against advanced pollution measurement systems. The project’s goal is to empower community groups and individuals to measure air pollution, identify its sources, and interact with officials to foster cleaner environments.
Flatburn has undergone extensive testing in cities like New York and Boston, collecting millions of data points to establish its reliability in measuring fine particulate matter and nitrogen dioxide. While results showed that Flatburn’s measurements are slightly lower than standard systems, the correlation remains strong, indicating its effectiveness with proper adjustments. Researchers provided detailed instructions for building and using Flatburn, emphasizing community engagement in addressing pollution sources. Although challenges like sensor drift and operational lifespan exist, the project aims to democratize environmental data, equipping people with analytical skills to influence policy and foster cleaner air.
