Abstract
In an era of rapid urbanization and increasing environmental concerns, the way we design and manage buildings is undergoing a significant transformation. At the forefront of this change stands the Internet of Things (IoT), revolutionizing the concept of "smart buildings" and creating interconnected spaces that are not only efficient and sustainable but also enhance occupant comfort and well-being. This article delves into the multifaceted world of IoT-enabled smart building technologies, exploring key sensor systems, innovative applications, and potential challenges, as we paint a picture of the future where buildings themselves become dynamic and responsive agents in the urban landscape.
