What is Internet of Things?
The Internet of Things(IoT) integrates physical objects such as home appliances, automobiles, and medical devices with sensors and software that connect them to the internet. This allows devices to gather, communicate, and analyze data, creating smarter systems that improve decision-making and efficiency.
Examples of Internet of Things in Action
- Smart Thermostats: Learn user preferences to optimize heating.
- Wearable Fitness Trackers: Monitor health statistics and upload data to applications for analysis.
Key Components of Internet of Things
1. Devices and Sensors
These physical devices collect data such as temperature, humidity, motion, or location. They range from simple household appliances to complex industrial equipment.
2. Connectivity
IoT devices communicate data using various protocols, including:
- Wi-Fi
- Bluetooth
- Zigbee
- Low-power wide-area networks (LPWAN)
The choice of protocol depends on factors like application and transmission range.
3. Data Processing and Analytics
Collected data is processed locally (edge computing) or in the cloud.
- Edge Computing: Enables real-time analytics.
- Cloud Computing: Supports large-scale computation and storage.
4. User Interface
IoT user interfaces allow users to manage devices and monitor analytics. Interfaces include mobile apps, websites, or voice assistants.
