An intelligent urban measurement project that’s changing our understanding of cities and urban life. The Array of Things (AoT) is a collaborative effort among scientists, universities, federal and local government, industry partners, and communities to collect real-time data on urban environment, infrastructure, and activity for research and public use. AoT uses an open intelligent sensing and edge computing platform called Waggle, developed at Argonne National Laboratory. AoT was funded primarily by the U.S. National Science Foundation.
