What is IoT
• The Internet of Things (IoT) is the network of physical objects—devices, vehicles, buildings and other items—embedded with electronics, software, sensors, and network connectivity that enables these objects to collect and exchange data.
• IoT allows objects to be sensed and controlled remotely across existing network infrastructure.
Introduction
• We are at the brink of a new Industrial revolution, one characterised by Cyber- Physical Systems. It is the 4th Industrial revolution
• 1st: Steam Engine - Mechanisation
• 2nd: Electricity - Mass production
• 3rd: Computer and Automation
• Estimated spending on IoT by 2020 is $6T.
• It is the next big business and employment opportunity.
IoT Applications
• Environmental Monitoring
• Home and Building Automation
• Manufacturing
• Infrastructure Management
• Medical and healthcare systems
• Transportation
IoT Components
• Physical objects: Things that can sense or affect the physical environment.
• Virtual objects: e.g. electronic tickets, id cards, wallets.
• People - humans who control the environment via mobile apps.
• Services: e.g. cloud services used to optimize business processes by integrating device data.
• Platforms: middleware used to connect IoT components together
• Networks: various wireless and wire line technologies, standards, and protocols.
