The city of Chicago has partnered with researchers at the University of Chicago and Argonne National Library, among several other corporations, on a project that will allow city officials and the public to instantly access data on air quality, noise levels and pedestrian and vehicular traffic, according to USA Today.

Last week, two of 500 modular sensor boxes, also called nodes, were installed under the "Array of Things" project, the first initiative of its kind in the U.S. Plans to replicate the project in more than a dozen other cities, such as Atlanta, Chattanooga, Tenn., and Seattle, are already underway.
