Detailed Explanation
Evolution of IoT
The concept of IoT has evolved from the convergence of wireless technologies, micro-electromechanical systems (MEMS), microservices, and the internet. The convergence has helped tear down the silos between operational technology (OT) and information technology (IT), enabling unstructured machine-generated data to be analyzed for insights to drive improvements.
Core Components of IoT
- Devices (Things): Physical objects equipped with sensors and actuators that collect data and perform actions.
- Connectivity: Communication networks that allow devices to exchange data with each other and with centralized systems.
- Data Processing: The computation that transforms raw data into meaningful information.
- User Interface: The platforms through which users interact with the IoT system, such as applications and dashboards.
How IoT Works
- Data Generation: IoT devices generate data through sensors that detect changes in the environment, such as temperature, motion, light, and more.
- Data Transmission: The data is transmitted over networks using protocols like Wi-Fi, Bluetooth, Zigbee, or cellular networks.
- Data Processing: Received data is processed either locally (edge computing) or in centralized servers (cloud computing) to derive actionable insights.
- Action: Based on processed data, actions are taken automatically or recommendations are provided to users.
