The smartest smart city.
"A planned city in Portugal called PlanIT Valley is expecting to install more than 100 million sensors. The sensors will be used for a whole range of services, including smart transit and parking; emergency services dispatching; energy monitoring and management in smart buildings; and monitoring infrastructure condition and performance. Sensors in homes will be set-up to identify water leaks and will be capable of autonomously notifying a plumber. The planned city sensors will feature the equivalent to nearly 450 sensors per capita."
