Study Notes
What is IoT?
- The Internet of Things combines physical objects with electronics, software, sensors, and network connectivity.
- It allows the remote sensing and control of these objects through existing networks.
- This integration improves efficiency, accuracy, and economic benefits by connecting the physical world with computer-based systems.
Examples of IoT devices
- Heart monitoring implants
- Biochip transponders on farm animals
- Electric clams in coastal waters
- Automobiles with built-in sensors
- DNA analysis devices for environmental/food/pathogen monitoring
- Field operation devices that assist fire-fighters in search and rescue operations
IoT Ecosystem Components
- Device manufacturers: create sensors, actuators, and smart appliances
- Network service providers: operate and manage networks
- Cloud service providers: provide data centers, databases, and data warehouses
- Platform providers: offer middleware, software development kits (SDKs)
- 3rd party application developers: create analytics tools and APIs
GE Example
- GE uses sensors in jet engines, turbines, and wind farms for predictive maintenance.
- Analyzing data in real-time saves time and money.
IoT History
- The concept of the Internet of Things gained popularity in 1999.
- The Auto-ID Center at MIT and related market analysis publications promoted the idea.
- RFID was considered essential for IoT at that point.
IoT as a Network of Networks
- IoT consists of interconnected networks of devices and computers.
- Intermediate technologies like RFID and wireless connections enable connectivity.
- Added security, analytics, and management capabilities enhance IoT's power.
Tagging Things
- RFID allows real-time item traceability and addressability.
- Sensor data collection tracks changes in the physical status.
- Miniaturization and Nanotechnology allow smaller devices to interact and connect.
