Internet of Things

The **Internet of Things (IoT)** refers to a network of physical devices connected
to the internet that collect, exchange, and sometimes act on data.

These devices include:
* Smart home devices (lights, thermostats, cameras)
* Wearables (smartwatches, fitness trackers)
* Industrial machines
* Connected vehicles
* Medical monitoring devices
* Agricultural sensors

How IoT Works:
1. **Sensors/Devices** – Collect data (temperature, motion, location, etc.)
2. **Connectivity** – Send data via Wi-Fi, Bluetooth, cellular, or other networks
3. **Data Processing** – Cloud or edge systems analyze the data
4. **User Interface** – Apps/dashboards let users monitor and control devices

Key Components of IoT
* **Sensors & Actuators** – Detect changes and perform actions
* **Network Connectivity** – Internet communication
* **Cloud Computing** – Data storage and processing
* **AI/Analytics** – Decision-making and predictions
* **Security** – Protects data and devices

Applications of IoT:
* **Smart Homes** – Automated lighting, security, appliances
* **Healthcare** – Remote patient monitoring
* **Agriculture** – Soil and weather monitoring
* **Manufacturing** – Predictive maintenance
* **Transportation** – Fleet tracking, smart traffic
* **Smart Cities** – Waste management, energy efficiency
