The Internet of Things (IoT) refers to a network of physical devices—such as sensors, appliances, vehicles, and other embedded systems—connected to the internet and capable of collecting, sending, and receiving data. How It Works: Devices/Sensors: Collect real-world data (e.g., temperature, motion, GPS, etc.). Connectivity: Data is transmitted via Wi-Fi, Bluetooth, Zigbee, LoRa, or cellular networks to the cloud or local servers. Data Processing: Cloud platforms or edge devices analyze the data to make decisions (e.g., turn off lights if no motion is detected). User Interface: Users can interact with devices through apps, dashboards, or automated responses (e.g., smartphone app to monitor home security).
