Exercises
1. Design a solution to solve traffic light breaking problem using IoT. Think of sensors that
can track cars that are breaking traffic lights and inform about these cars to authorities.
Note down all the protocols that you will be using in this solution and your data
communication strategy.
2. Think of sensors that can connect hospitals with medical suppliers so ordering of medical
related supplies, medicines, one time usable equipment such as syringes and saline will be
smooth and hospitals will always have these supplies in sufficient quantities.
3. Think of an analytical solution that can parse all the data collected from all the sensors
in an Airport Baggage Tracking IoT deployment. How can airlines and airport use this
data and what type of management benefit they will get out of this?
Review Questions
1. How many different types of IoT protocols are there? Name them.
Which protocol enables communication between two network connected devices?
2. How many types of sensors are available?
3. What type of sensors will be useful to detect water leakage at home?
4. Which components play an important role in IoT?
5. Explain Bluetooth protocol and compare it with Wi-Fi.
6. What is the importance of Data Management in IoT?
7. What is streaming analysis and when to use it?
8. Explain various data communications such as device-to-device, device-to-cloud, and
device-to-gateway.
9. What is the use of motion detection sensor?
10. What is lightweight endpoint? Explain in details.
11. What is IR sensor and how to use it?
12. When do you use ZigBee protocol?
13. What is the use of pressure sensor?
14. Explain IoT Data Management in details.
Challenge Questions
1. Can you use Bluetooth and Wi-Fi together?
2. Can RF sensor work under water?
3. Can IoT implementation be done between WAN and NAN?
4. How can you make two sensors that are on different network platform talk to each other?
Project Idea
Every year a lot agricultural crops go bad because of various factors and farmers end up losing their
entire income and go bankrupt. Think of an IoT solution that will predict soil health, soil water
retention capability, requirement of fertilizers, etc. to reduce the crops waste. List all the sensors
you will need and all those sensors can connect together. Design a complete architectural plan for
this IoT deployment and consider using mobile devices for IoT Data management.
