Introduction
The Internet of Things (IoT) refers to a network of physical objects embedded with sensors, software, and other technologies that connect and exchange data with other devices and systems over the internet. These objects range from everyday household items to sophisticated industrial tools.
Historical Context
The concept of IoT dates back to the early 1980s when a group of Carnegie Mellon University students modified a Coca-Cola vending machine to report its inventory status. However, the term “Internet of Things” was coined by Kevin Ashton in 1999 during his work at Procter & Gamble.
Types of IoT Devices
Consumer IoT
- Wearables: Smartwatches, fitness trackers.
- Home Automation: Smart thermostats, lighting systems, refrigerators.
Industrial IoT (IIoT)
- Manufacturing: Smart factories, predictive maintenance systems.
- Energy: Smart grids, oil and gas monitoring systems.
Enterprise IoT
- Retail: Smart shelves, inventory management.
- Healthcare: Remote monitoring, smart medical devices.
Key Events
- 1999: Term “IoT” coined by Kevin Ashton.
- 2008: The number of connected devices surpassed the number of humans on the planet.
- 2011: IPv6 launch, significantly expanding IP addresses available for IoT.
Detailed Explanations
How IoT Works
IoT systems typically involve four key components:
- Sensors/Devices: Collect data from the environment.
- Connectivity: Data is transferred to the cloud via a network.
- Data Processing: Cloud software processes the data.
- User Interface: Processed data is delivered to the user through a dashboard or notification.
Key Technologies
- RFID (Radio Frequency Identification): Used for tracking and identifying objects.
- Wireless Sensor Networks (WSN): Consist of spatially distributed autonomous sensors.
- Bluetooth Low Energy (BLE): Enables short-range communication between devices.
