Chicago is working on implementing all 500 sensors throughout the city to take pictures, monitor movement and record sound. The $7 million investment will collect data about the city and its community to help authorities and businesses improve daily life and traffic. The nodes, shaped like a beehive, play an important role in tracking pedestrian and vehicle movement, in measuring temperature and pressure, pollen, and will even assess air quality based on carbon monoxide or nitrogen dioxide levels. The data is stored in the cloud and the community is fully protected.”]
