INTERNET OF THINGS




Internet of Things= the network of physical objects, devices, vehicles, buildings and other items which are
embedded with electronics, software, sensors and network connectivity, which enables these objects to collect
and exchange data

- 2008: grens overschreden: meer objecten dan mensen met internet geconnecteerd
- 2015: 5 miljard devices
- 2020: 50 miljard devices




3 grote technologieën liggen aan de basis van IoT:

- Sensoren (1)

, - Communicatie (2)
- Distributed embedded software (3)
