Internet Of Things
How IoT works
- Sensors: Monitor things like temperature, motion, and other changes in the environment.
- Actuators: Receive signals from sensors and respond to those changes.
- Cloud: Receives data from sensors and devices. Software processes the data and may take action, such as sending an alert or adjusting the sensors or devices.
Applications of IoT
- Patient treatment: IoT systems can help with patient treatment, detecting medical priorities, and supporting medical staff.
- Hospital maintenance: IoT systems can help with the maintenance of medical devices.
- Smart cities: IoT systems can collect data on infrastructure needs, transportation requirements, crime, and safety.
- Big data analytics: IoT systems generate large amounts of data that companies can analyze.
History of IoT
- The term "Internet of Things" was coined in 1999 by computer scientist Kevin Ashton.
- Ashton proposed putting radio-frequency identification (RFID) chips on products to track them through a supply chain.
