Assignment Brief and Guidance:
You currently work as a product developer for a new startup where you design IoT products
for the consumer, corporate, government and defence clients. As part of your role your
manager has tasked you to plan and develop a new IoT product, service or application for
a potential client. You are required to identify a target user and conduct tests with this user
and include this feedback into multiple iterative versions of your product.
Part 1 (Assignment 1):: For the first part, you must:

•

•

Plan an IoT application for a specific target end user and the tests you intend to
conduct with this user. This plan will be in the form of a document and will include
supporting evidence and material, such as user personas and customer journey
maps.
Create multiple iterations of your application and modify each iteration with
enhancements gathered from user feedback and experimentation. This will follow
the pathway outlined in your plan.(log book,)

Part 2 (Assignment 2): For the second part, you must produce a report to prove that:
•

•

1. Develop IoT application (P5)
1.1 Project introduction
1.1.1 Project overview

As already indicated in the report. We shall build a project in this report to fulfill the demands of
investors. At the same time, it will assist to enhance people's suitable parking while moving into co
memorial centers.
It is a model that contains sensors, lights, noises, and, most importantly, an LCD screen that displays
the warning signals to everyone. Furthermore, when pulling up to the parking lot, there is still a legal
line, just as in other parking lots.
It is a cylinder; all of the indicator lights illuminate, and the LCD displays its operations. And each
parking area will have its own set of equipment. The distance will be used by the sensor and display
to measure and show the required information. The following is how it works:
+ The parking place is empty; the green light turns on, and the LCD displays the words "Empty." It
indicates that the parking space is vacant. And the distance between that cell and becoming empty is
5m.
+ The car is reversing, and the distance is between 5m and 2.5m. The yellow light will appear
immediately, and the instruction will be to proceed deeper.
+ When the car is less than 2.5m and larger than or equal to 1m, the red light illuminates and the
message "Parking" appears.
+ Finally, if the automobile backs into the parking lot for more than 1m, the buzzer will ring and the
words warning will appear on the screen.
Here are some images of the gadget as it was developed in Tinkercad. It aids us in determining if the
circuit and equipment will operate consistently when put to use.

1.1.3 Project Plan
Everyone on our team worked on the project for a total of four weeks.
•
•
•

The first and second week: we came together to agree on the idea and contribute
the code together.

The third week: we came up with the idea of building the model and assembling the
components together.
Fourth week: We fix the bugs encountered by the device, test them one last time
and write the report.

2. Run end user experiments and examines feedback (P6, P7)
To get user input, our team decided to conduct a brief survey. The primary goal of the poll
was to determine how people interact with our cutting-edge sensor parking. We plan to
investigate in depth:
- When the project is finished.
- The project's flawless score.
- The project's unfinished point
Finally, we collected three clients and demonstrated how distance sensors for automobiles
operate. Then we asked them to fill out our survey.

3. Discuss the drawback in your system and solutions for improving (P6, P7)
With our system, after testing and collect surveys and questionnaire from user’s feedback,
we realize some problem and drawback below:
Problem and Drawback

Solutions for improving

Because each grid, each car need a device, Optimization area, calculate number of device

4. Conclusion
In conclusion, after working together on this project, we now know what the Internet of
Things is and how to use it. We also know how to work together and are learning how to use
various electrical devices with tools and hardware such as Arduino. Furthermore, because it
only mimics a portion of the actual parking system, our approach needs be greatly improved
in order to be useful.
