Nowadays, a lot of people sport fitness trackers - wearable devices that monitor a person’s steps, heart rate, exercise habits and more. Well, the city of Chicago is hoping to expand on the idea to track the city’s fitness. The project — called The Array of Things (AoT) — will install modular sensor boxes on city street light posts that measure things like climate, air quality and noise.

The project is a collaboration between the University of Chicago, the Argonne National Laboratory, the School of the Art Institute of Chicago, Northern Illinois University and the University of Illinois at Urbana-Champaign.
