The convergence of Embedded Systems and the Internet of Things (IoT) is reshaping modern technology, enabling intelligent, connected devices across domains such as healthcare, transportation, and smart infrastructure. This book provides a comprehensive foundation, bridging theory and practical implementation. It introduces core concepts of embedded systems, including real-time operation, application-specific design, and interaction with physical environments. The text explores key modelling approaches such as Finite State Machines, Dataflow, and Discrete Event systems, offering systematic methods to design complex systems. It also highlights critical design challenges like power efficiency, reliability, cost constraints, and performance optimization. Practical insights into processor selection, hardware-software co-design, and system architecture equip readers with essential engineering skills. A notable strength of the book is its application-oriented approach, supported by real world case studies such as Automated Weather Stations for disaster monitoring. These examples demonstrate how embedded and IoT systems contribute to safety, sustainability, and innovation. Overall, this book serves as a valuable academic and professional resource, preparing readers to design scalable, efficient, and intelligent embedded solutions in an increasingly connected world.
