Introduction
The Internet of Things (IoT) is no longer a concept of the future. It is present in our daily lives, connecting objects, devices, and systems that once worked in isolation. From smart refrigerators to autonomous cars, from smart cities to connected farms, IoT is revolutionizing the way we live, work, and interact with the world.
In this article, you will understand what the Internet of Things is, how it works, where it is being applied, and how it is shaping the future of society, the economy, and technology.
1. What Is the Internet of Things (IoT)?
The Internet of Things is the connection of physical objects to the internet, enabling them to collect, transmit, and receive data autonomously or interactively.
Examples of connected objects:
- Smart refrigerators that alert when a food item is running low.
- Thermostats that adjust the temperature based on your routine.
- Smartwatches that monitor health and physical activity.
- Connected cars with navigation, security, and automation systems.
- Sensors in factories that monitor production in real-time.
2. How Does IoT Work?
Main Components:
- Devices (things): Physical objects equipped with sensors, actuators, and communication chips.
- Connectivity: Wi-Fi, 5G, Bluetooth, LoRa, NB-IoT, and other technologies that enable data transmission.
- Processing: Data is sent to local servers (edge computing) or to the cloud, where it is processed.
- User Interface: Apps and dashboards that allow monitoring and interaction with devices.
3. IoT Applications in Daily Life
Smart Homes:
- Automatic lighting.
- Smart locks.
