Smart Cities: How IoT is Redefining Urban Living
The rise of smart cities is transforming the way people live, work, and interact with their environment. By leveraging the Internet of Things (IoT), cities are becoming more efficient, sustainable, and citizen-friendly. From connected traffic lights to energy-saving smart grids, IoT is playing a vital role in shaping the future of urban living.
What is a Smart City?
A smart city uses technology and data-driven systems to improve urban infrastructure and services. IoT devices collect real-time data from sensors, cameras, and connected networks, which city authorities use to make smarter decisions. The ultimate goal is to improve the quality of life, reduce resource consumption, and enhance public safety.
