The Internet of Things (IoT) comprises several functional blocks that enable its seamless operation. At its core, IoT devices gather data from sensors embedded in various environments. These sensors detect changes in temperature, humidity, motion, and more, transmitting this information to a central processing unit. The processing unit analyzes the data and triggers actions based on predefined parameters. Functional blocks of IoT, including sensing, processing, communication, and actuation, synergize to create interconnected systems revolutionizing industries worldwide.
