Building a Smart City through an of Internet of Things (IoT)

India with a population of 1.29 billion people ranks the 2nd in the world after China. Over 30% of this populace lives in urban areas and it is expected that by the year 2030 40.76% of the population will be residing in cities. As a result it becomes increasingly necessary to make cities smarter in order to enable the city inhabitants and the governing system to acquire real time data regarding their surroundings supplied through an IoT to make the necessary decisions and act accordingly so as to have a better standard of living as well as plan for the future. The Internet of Things (IoT) enables a system consisting of a group of heterogeneous sensors which can be seamlessly incorporated into the framework of cities and provide real time monitoring to achieve this goal. Environmental monitoring as well as future planning for the city can be aided by observing the results put forth by the system. This paper focuses on the implementation of five aspects including temperature, pollution and noise monitoring along with traffic light control and street light control. The project aims at reducing pollution levels and creating a better, safer and improved environment for city life.
