What is IoT (Internet of Things)?

The Internet of Things (IoT) refers to a network of interconnected devices and objects that communicate with each other over the internet. These devices are embedded with sensors, software, and other technologies, allowing them to collect, exchange, and act on data, often without human intervention.

How IoT Works

  • Sensors and Devices:

    • IoT devices are equipped with sensors to collect data (e.g., temperature, motion, humidity).

  • Connectivity:

    • Data from these devices is transmitted over the internet or local networks using protocols like Wi-Fi, Bluetooth, or Zigbee.

  • Data Processing:

    • The collected data is sent to cloud servers or edge devices for processing and analysis.

  • Action:

    • Based on the data analysis, IoT systems can take actions, send notifications, or provide insights.

Key Components of IoT

  1. IoT Devices:

    • Physical objects such as smart thermostats, wearable devices, and industrial sensors.

  2. Network:

    • Communication protocols and technologies that connect devices to the internet (e.g., Wi-Fi, LTE, 5G).

  3. Cloud Platforms:
