Towards a Smart Sustainable City: Air Pollution Detection and Control using Internet of Things

Smart cities have become an essential and global need; they enhance the infrastructure to mitigate the problems caused by the rapid pace of the urbanization. The main goal is not only achieving a smart city but to realize a smart sustainable city, to achieve the balance of the environment alongside the balance of the city's technology evolution. The Internet of Things (IoT) technology is the most popular technology used in smart cities due to its efficiency in wide varieties of applications. Although the IoT is yet to fully emerge, the energy demand has proven to be significantly increased and will keep on increasing over the upcoming years, that's why it's crucial to investigate the Green IoT. One of the most challenging issues in cities is pollution especially air pollution. Air pollution will become a catastrophe with technological advancement if cities turned a blind eye to it. It has a direct effect on people's health as well as the ecosystem. From this point, this paper suggests a green IoT based efficient system that detects and monitor the outdoor air pollution level; the system is powered by renewable energy. The system monitors the pollution level; if the pollution level exceeds the acceptable pollution level, it takes a decision to notify the authorities who can use this data in planning preventive actions and take measures to stop the continuous harmful air pollution effects and prevent the evolution of this phenomenon.
