The Internet of Things (IoT) refers to a vast network of interconnected physical devices embedded with sensors, software, and other technologies that enable them to collect, exchange, and act on data over the internet. These "smart" devices range from everyday household objects (e.g., refrigerators, thermostats) to industrial machines (e.g., sensors in manufacturing plants), creating a seamless flow of information between the physical and digital worlds.
1. Devices & Sensors: Hardware that detects changes in the environment (e.g., temperature, motion).
2. Connectivity: Networks (Wi-Fi, Bluetooth, 5G, LPWAN) that transmit data to the cloud or other devices.
3. Data Processing: Cloud platforms or edge computing systems analyze raw data to extract insights.
4. User Interface: Apps or dashboards that allow users to interact with IoT systems (e.g., smartphone controls for smart lights).
