The Internet of Things (IoT) has revolutionized the way we live, work, and interact with our surroundings. Sensor systems play a crucial role in these technological advancements, and their integration with IoT has revolutionized the way data is acquired, processed, and utilized. This book offers a structured understanding of sensor technologies, principles, applications, and their integration into IoT systems, thereby bridging the gap between sensors and IoT applications.This book goes beyond theoretical explanations and stands out as a comprehensive and practical guide with a strong focus on real-world applications. It reveals some interesting aspects of such fascinating interactions between sensors and the IoT — in particular, cutting-edge technologies and possibilities ranging from smart homes to industrial automation and beyond. It also offers a detailed exploration of sensors and the measurement principles characteristic of sensors designed to detect and measure specific environmental parameters — especially those equipped with the capability to convert the collected data into electronic signals, which can then be processed and communicated to other connected devices through the internet. Data-based innovation in driving technological advancements is also addressed, and Intellectual Property (IP) is explored as a key element in bridging the gap between scientific research and marketable products.This book is an indispensable guide for students, researchers, and professionals alike. Its comprehensive approach to sensor technology makes it a valuable resource for scientists, engineers, and decision makers in industry.
