The Introduction to Internet of Things (IoT) self-paced course provides a solid foundation in the rapidly growing field of connected devices and smart systems. Designed for students, hobbyists, and professionals from diverse backgrounds, this course introduces the core concepts, architecture, and technologies that make up the IoT ecosystem. Learners will explore how sensors, microcontrollers, communication protocols, and cloud platforms work together to collect, transmit, and analyze data in real time. Key topics include IoT hardware (such as Arduino and Raspberry Pi), wireless communication (Wi-Fi, Bluetooth, MQTT), data processing, and integration with cloud services like ThingSpeak or AWS IoT. Practical examples and hands-on projects help learners build simple yet functional IoT applications, such as home automation, environmental monitoring, or smart agriculture. By the end of the course, participants will have a clear understanding of how IoT systems are designed, implemented, and scaled, opening the door to more advanced applications in smart cities, healthcare, industry, and beyond.
