The document discusses Internet of Things (IoT) and home automation systems. It defines IoT as internet-connected physical objects that can collect and share data to solve problems. It explains that a home automation system allows smart objects like phones, security systems, and thermostats to interact and share data using technologies like WiFi and APIs. The document outlines some of the challenges of IoT systems, including issues with protocols, APIs, power usage, security, and data privacy, and provides an example high-level architecture of how an IoT home automation system may be implemented.

2. Agenda
• What is IoT
• Why IoT?
• Home automation system architecture

3. About

4. What is IoT?
• Internet ofThings
• Internet connected objects (things) working together to solve a business problem
• Has been around for quite a while, but only recently has become affordable for
personal use

5. What are the “Things” in the IoT?
• Could be anything
• Physical
• Virtual

6. Why IoT?
• Generate, collect, process and use acquired information to make better
decisions
• Smart objects: Make things that weren’t meant to talk to each other
interact smartly
• Gartner says the Internet ofThings installed base will grow to 26 Billion
units by 2020; I want to be well aligned and prepared for that

7. Smart objects: Make things that weren’t
meant to talk to each other interact smartly
• Phone  Location detection, presence detection Thermostat
• Doorbell activation  CCTV takes picture Email + SMS +Tweet
• Fire Alarm  Email + SMS
• Security System CCTV  Email + SMS
• Climate control  presence @ home & weather forecast
• Hot water tank 1   Hot water tank 2   our presence, weather forecast
• Dog CCTV + Email
• Weather notifications  email

8. Influence others to reduce their carbon
footprint by sharing socially your metrics

9. Challenges
• Global cooperation
• Proprietary and incompatible protocols
• Lack of APIs
• Example: Common external power supply
• Technological challenges
• Power usage
• Scalability
• Security
• Communication mechanisms
• Ethics, control society, surveillance, consent and data driven life
