The Internet of Things concept
What is Internet of Things?
The Internet of Things (IoT) refers to the network of physical objects embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the internet. These devices range from household objects to industrial tools.
- Connectivity: IoT devices connect to the internet and to each other
- Data collection: Devices gather environmental information
- Automation: Many IoT systems operate with minimal human intervention
- Intelligence: IoT devices have processing capability
Evolution of connected technology
Brief History and Evolution
While the concept predates the term, Kevin Ashton reportedly coined "Internet of Things" in 1999 while working at Procter & Gamble, recognizing RFID technology's potential to connect the physical world with the internet.
Key IoT milestones include:
- 1982: First internet-connected appliance (Coke machine at Carnegie Mellon)
- 1990: Internet-controlled toaster created by John Romkey
- 1999: Term "Internet of Things" coined by Kevin Ashton
- 2008-2009: First IPv6 conference, official birth of IoT
- 2010s: Rapid growth of IoT across industries
- Present: Billions of connected devices worldwide
How IoT Works
The basic IoT architecture involves four main components:
- Sensors/Devices: Collect data from the environment
- Connectivity: Transmit data via cellular, Wi-Fi, Bluetooth, etc.
- Data Processing: Process data in cloud or on edge devices
- User Interface: Present information through apps, dashboards
