IoT Foundations: Connecting Devices, Sensors, and Cloud Systems

The Internet of Things is transforming how we interact with the physical world, but building connected systems requires a solid grasp of both hardware and software. This course guides you through the fundamental building blocks of IoT without assuming prior hardware experience. You will transition from understanding basic sensor data to conceptualizing full-scale IoT architectures, learning how devices communicate, how data is secured, and how to route information to the cloud for analysis. What you'll learn: - Understand core IoT terminology, architecture models, and hardware components like microcontrollers and sensors. - Compare key communication protocols including MQTT, HTTP, and CoAP for efficient data transfer. - Explore modern edge computing concepts to process data closer to the source and reduce latency. - Learn security best practices for securing device identities, data transmission, and firmware updates. - Map out cloud integration strategies to store, analyze, and visualize sensor data effectively. The course begins with foundational definitions and hardware basics, then moves through networking protocols, security frameworks, and practical cloud integration patterns. This course is designed for software developers, system architects, and tech enthusiasts who want to enter the world of IoT, with no prior hardware or electronics experience required.
