By 2018, a network of 500 sensor nodes situated around Chicago will monitor air quality, climate, traffic, noise and other factors that affect the environment of the city. The network is called the Array of Things, an urban sensing project that is being described as a "fitness tracker for the city," collecting real-time data that can be used to help improve Chicago's infrastructure, provide hyper-local forecasts and help you get to work on time. Funded by a $3.1 million grant from the National Science Foundation, the project marks a collaboration between the city and researchers at the University of Chicago and Argonne National Laboratory.
