The Internet of Things (IoT) is the study of interconnected physical devices equipped with sensors, software, and network connectivity, enabling them to collect and exchange data with minimal human intervention. This subject introduces students to the foundational principles of IoT, covering its architecture, enabling technologies, and broad applications across various industries. Students will learn about real-time data sensing, embedded systems, wireless sensor networks, cloud computing, and big data analytics. The curriculum emphasizes hands-on learning with IoT prototyping platforms like Arduino and Raspberry Pi, along with the development of smart solutions for domains such as home automation, energy, healthcare, agriculture, and smart cities. By the end of the course, students will understand how IoT integrates devices into intelligent systems, supporting improved efficiency, automation, and decision-making in the digital world.
