Internet of Things

Introduction: What is the Internet of Things (IoT)?

The Internet of Things (IoT) is a network of physical devices — from household appliances to industrial machines — connected to the internet, collecting and exchanging data without human intervention. These “smart” devices use sensors, software, and other technologies to interact with the world and each other, transforming how we live, work, and do business.

Key Components of IoT

1. Devices & Sensors

   • Physical objects embedded with sensors (temperature, motion, humidity, GPS).

   • Examples: smartwatches, smart TVs, home thermostats, factory machines.

2. Connectivity

   • Devices communicate via Wi-Fi, Bluetooth, 5G, Zigbee, LoRaWAN, etc.

3. Data Processing

   • Collected data is processed using edge computing, cloud computing, or local devices.

4. User Interface

   • Interaction happens via smartphones, apps, dashboards, or automated actions.

How IoT Works

1. Sensors collect data (e.g., temperature in a room).

2. The device sends this data to the cloud or local servers.

3. Data is analyzed to make decisions (e.g., turn off the AC when the room is cool).

4. The system acts or alerts the user.
