Introduction to Internet of Things (IoT) and Applications

This module introduces students to the fundamental concepts of the Internet of Things (IoT). It covers the definition of IoT, historical aspects of its development, and the comprehensive process of creating an IoT application or system from initial concept to product certification. The module also explores various applications of IoT across different sectors including industrial, agricultural, and healthcare domains. Students will learn about the architecture required for IoT implementations, how to design effective IoT solutions, and examine real-world applications to understand practical implementation challenges and benefits.
