- 2. ABOUT ME Education: Electrical/ Control/Computer/Communication Engineering Job: IoT Systems Engineer @ Wasslz, Sales Manger @ Makerpot.com Skills: Systems Administration, Computer Networking, Computer Programming, Embedded Systems, Information Security, Curiosity,Asking, Reading
- 3. What is IoT? Any thing Anywhere Anytime
- 4. WHAT IS IOT? • The Internet of Things (IoT) is the network of physical objects or "things" embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data. • IoT allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration between the physical world and computer-based systems, and resulting in improved efficiency, accuracy and economic benefit. • 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. 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 of Things installed base will grow to 26 Billion units by 2020; I want to be well aligned and prepared for that
- 6. WHY SHOULD I LEARN ABOUT IOT? • Emerging technologies • Growing IoT Services and Applications in various areas including smart cities, healthcare, transport, logistics, retail, safety and security, etc. • Business trends and new opportunities 6
- 7. 7 Sensor devices are becoming widely available
- 8. 8 More “Things” are being connected
- 9. 9 People Connecting to Things Motion sensor Motion sensor Motion sensor ECG sensor Internet
- 10. 10 Things Connecting to Things - Complex and heterogeneous resources and networks
- 11. 11 11 “Thing” connected to the internet Source: CISCO

- 20. LET’S DO IT
- 21. PRE-REQUISITES 21 We expect you are familiar with hardware systems. We expect you know about basic communication and networking. We expect you have a knowledge of the object oriented programming (especially C).
- 22. MESSAGE QUEUING TELEMETRY TRANSPORT (MQTT) • Lightweight messaging protocol designed for sensors and devices with • Flaky network connectivity • Low computing power • Connections where bandwidth is at a premium Works on top of TCP Transport Layer Security (TLS) Protocol specification is open source
- 23. MESSAGE QUEUING TELEMETRY TRANSPORT (MQTT) Applications: • A way to obtain real world data • information is gathered by an increasing number of sensors and devices deployed all over • A way to provide real time information • E.g. Locate an item in a supply chain • Accurate current load of a any system (e.g. electricity meters) • Current status of a system (level of liquid in a container, temperature, pressure etc.) • A way to connect all the devices and sensors directly to your messaging infrastructure
- 24. MQTT Architecture • All three clients open TCP connections with the broker. Clients B and C subscribe to the topic temperature . MQTT Topics and Topic Matching In MQTT, topics are hierarchical, like a filing system (e.g., kitchen/oven/temperature).
- 25. MQTT Architecture • At a later time, Client A publishes a value of 22.5 for topic temperature. The broker forwards the message to all subscribed clients. MQTT Topics and Topic Matching In MQTT, topics are hierarchical, like a filing system (e.g., kitchen/oven/temperature).
