The document describes a dust monitoring project aimed at notifying households when to clean. A team developed a novel dust sensor that measures concentrations without becoming covered in dust over long periods. When dust levels exceed a threshold, the monitor alerts users and triggers a smart vacuum to start cleaning. The monitor was tested for 5 months, successfully measuring dust levels without sensor damage.

2. Aim: To design a dust monitor that notify households on when to clean their
apartment.
Description: Most of the cheaper dust monitors have the challenge that they
start producing erratic readings after long usage because their sensing
element has been covered with dust. In this project a team of 4 persons looked
on the existing technologies for detecting dust and came up with a novel
approach to measure dust concentration. Once the concentration goes above a
harmful threshold, the monitor alerts the user to clean the apartment. The
dust monitor data were used to start a smart vacuum cleaner.

3. Description:
Usually a smart vacuum cleaner uses time dependent command inputted
by the user to trigger the start function of the vacuum and then cleans the
apartment. That is, the user sets the time for the vacuum to start working.
But by using the signal from dust monitor, the vacuum becomes dust
concentrate dependent instead of being time dependent. Thus generating
the best time for the smart vacuum to start cleaning operation.

4. Role: I worked as a project manager and also a prototype engineer. In
addition I was responsible for procuring the necessary parts for the
prototype. The dust monitor was tested over a period of 5 months and the
data from the monitor were constantly sent to trigger the start command of
a smart vacuum cleaner.
Result: This dust monitor was able to measure concentration of dust in the
home over a long period of time without having its sensing element
damage.

7. Design Of A Baby Safety Guard (BSG)
 Aim: The aim of this project is to identify a social problem and
provide IoT solution.
 Result: After series of iterative ideation and conceptualization
session, we came up with a detailed design of a BSG device to
assist parents in better monitoring of their kids at home.
 My Role: I worked as a prototype engineer and also a programmer.

10. BREAK DOWN BIO
 Aim: To design an industrial composter for waste
management and also use it as an educational tool for kids
within the community.
 Description: Biolan Oy gave a project to a team of 12
students to design an industrial size biowaste composter
within a year. The composter must fulfill the following
requirements:

11. BREAK DOWN BIO
 It should be able to convert biowaste into manure in less than 6 weeks.
 It must be greater than the maximum size (900L) currently sold by the
company.
 It should be light and easily transportable.
 There should be a way to mix the waste during composting.
 It should be easily adoptable globally.
 It should operate well in all seasons.

12. The composter was designed based on the given requirements.
The design process was done by first carrying out detailed
research on the composting (biodegradation) process. This was
followed by series of brainstorming sessions on reducing the
composting time, Selecting the shape (exterior and interior) and
size. Then, detailed mechanical design analysis were carried out
on the selected shape, material, mixing mechanism, filling and
empting of composter, and monitoring system (level, temperature
and oxygen sensor). The design parameters were used to select
the best manufacturing technique for a working prototype. The
prototype was made with carbon fiber as can be shown in the
diagram below.

14. Role: I worked as a mechanical design engineer in this
project. During the project, I also assisted in prototyping and
testing/observing of the composter filled with biowaste during
winter.
Result: Our client was very satisfied with the design. Most of
the design requirements were met except for the
malfunctioning of mixing mechanism.

16. Aim: To design an affordable industrial smart cooker for preparing
African-based food with ease.
Description: The idea came about when a friend and I were called to
come assist in preparing (mixing) cassava staple for a 76 people’s
party. Ever since then, I have been brainstorming various ways to
make this preparation process ease. As time went on other friends
and colleague bought into the idea and we have been working on it
once in two weeks.
So far we are still conceptualization phase

Reflection
In working on these projects, I have improved and learnt some
valuable personal skills. These are:
 Good communication skills.
 A great team player.
 Good time and task management skills.
 Take leadership role when the need arises.
 Motivate other team members when they are falling short in
commitment.
 A good listener.
 Hardworking.
