1. Ideation

Research and Motivation Crafting a project emerges as a straightforward endeavor when guided by a well-defined plan and meticulous breakdown. However, translating this simplicity into reality proves to be a nuanced challenge, commencing with the inception of an idea – a point where my creative journey encounters a stumbling block. Since the beginning of December 2023, I’ve embarked on a quest to crystallize a concept that resonates with my aspirations. Regrettably, my progress has been impeded by the persistent emergence of technical hurdles, casting shadows on the potential realization of my envisioned accomplishment.

2. Plan

Plan My plan focus on 5 different stages Stage 1 (Spiral 1) Collecting Data AIR -- O2 .-- Co2 .-- Other air particles Small to mid size Made of wood Stage 2 (Spiral 2) Full of RGB’s Having a Screen Try changing the MCU Stage 3 (Spiral 3) Enhance the Shape and the quality of the packaging Build an app or just link it to blynk IOT ESP32 Stage 4 (Spiral 4) Add Speaker “Amplifier circuit is needed” Try make the size smaller Try making the device rechargeable “Stand alone” Charging circuit is required Stage 5 (Spiral 5) Build it using 3D printer Small rounded shape Easy to carry RGB, No Screen, IOT Connected Project Sketch System Diagram Schedule

3. Research

As planned I’m looking to create a device able to monitor the Surrounding air and check the quality of it. Air Quality Is a phrase refers to how clean the Air is and the amount of particles this air carry. When air quality is good, the air is clear and contains only small amounts of solid particle and chemical pollutants. Poor air quality, which contains high levels of pollutants, is often hazy and dangerous to health and the environment.

4. Sensors

As per My previous research I have to collect (CO2 , Particulate Matter (PM), Volatile organic compounds (VOC), Temperature, and Humidity) to obtain the quality of the indoor AIR so below I will list the needed sensors to collect the required data and their primary test. List of sensors. ID Sensor Measured Value LINK Price Datasheet 1 SCD30 CO2, Temp, Hum LINK $51.4 LINK 2 PMS5003 PM1, PM2.5, PM10 LINK $39.

5. IOT Cloud

As for the platform I want to use, I have previously tested two platform in the Interface and Application Programming week and I have decided to use thinger.io because it have more options in terms of data monitoring and data analysis after the data reaches the platform, But unfortunately this platform is not cheap if I want to expand the sensor data im collecting, So I decided to go with Arduino cloud and buy the maker plan So I can push all my data to the cloud and have 90 days of data retention.

6. Embedded Design and Fabrication

I have previously finished all testing for the hardware and the circuit is ready but it’s built using a breadboard now I need to design a new PCB board and make sure all my circuit is fully integrated on this board. As I have shown before my circuit is working 100% as I want and it is pushing data to the IOT platform as I want but I need now to make this complected messy looking circuit to a sleek lovely board with no complication when looking to it.

7. Housing Design and Fabrication

After finalizing all the Electrical requirement and the Board fabrication which the core of my project I need now a good representation for this core which can be a sleek piece on the corner or in the middle of the setting area which can’t go wrong when the person eye come to it and it attract the others attention. Previously I have decided to use ARABISC look on the front of the piece.

8. Wood processing and assembling

NOw After I have finalized the process of fabrication I need to assemble the housing all together with the PCB, But before that I need to make sure that this wood will stay in great shape as long as possible so i decided to give this wood some process to increase its life span and also to protect it from the Humidity and other weather conditions. This Process is the coating process as I will put a chemical liquid on the wood to protect it (This chemical is called Sanding Sealer)

9. Stand Design And Fabrication

After finalizing all the Housing Part and the needed to have every thing working as needed, Now I need to design and fabricate the stand for the housing to sit on and also enclosure for the PM2.5 Sensor –> This Is why I have decided to build this part. This part needs to be simple and compact, able to carry the housing piece and contain the PM2.5 sensor without any complications.

10. Final Product

Alhamdulillah, all our previous efforts have culminated in outstanding results. Every component is meticulously designed and functioning flawlessly. Moreover, the Electronics component, the core of our product, seamlessly transmits data to the Cloud as required. Now I will show Up the final assembly for all the parts together and a brief about what next in the future. This Is the final look of the project To know More about this in a brief LINK.

Overview

What will it Do?

I will develop a device capable of measuring CO2 Levels of the surrounding in addition to (Temperature, Humidity, TVOC, and Particulate Matter) then the device will push these Information to an online platform for monitoring.

Who has done what beforehand?

As per my research there are many companies in the field and there device is called {Indoor Air Quality Monitor} Such As:

What will you design?

I will design Everything in this project.

  • I will start by designing the PCB and then fabricating it going to soldering at the end, Then I will program it.

  • Secondly I will design the housing of my PCB and then the final shape of the device.

  • Finally I will design a stand to accommodate the device.

What materials and components will be used, From Where, and Cost?

Material:

  • Plywood : For the housing –> (Available in the LAB) (2240 X 1220 mm) LINK –> Cost (36.25$ USD)
  • PLA : For the PCB enclosure and for the device Stand. –> (Available in the LAB)LINK –> Cost (34.33$ USD)
  • Acrylic : Might be used to defuse the light. –> (Available in the LAB) (810mm X 610mm X 2.85mm) LINK –> Cost (8.24$ USD)

Component:

  • XIAO ESP32c3 –> LINK –> Cost (4.99$ USD)
  • SCD30 –> LINK –> Cost (51.4$ USD)
  • PMS5003 –> LINK –> Cost (39.95$ USD)
  • AGS02MA –> LINK –> Cost (4.95$ USD)

What parts and systems will be made?

The entire system is to collect the data from the surrounding through the sensor and then push them to Arduino Platform to be monitored.

  • This is what it meant to be for the project but we have the other part which is the housing for this system which is gonna be made out of wood and placed on PLA stand.

What processes will be used?

  • I will use the following :
  1. PCB Design and fabrication.
  2. Soldering the PCB and Programing.
  3. CAD design and milling fabrication using the MONOfab.
  4. CAD design and 3D printing
  5. I might use Laser to cut the acrylic.

What questions need to be answered?

I always love to design things but usually it ends there, a CAD design I can go back to when needed, But this time I would like to have this design alive and fabricate it using wood.

One of the struggle is the RGB I want to have it working – > THis RGB ring contains 16 addressable RGB which a bit means a good amount of current almost (20mA\RGB –> 16X20=320mA ) which indicate raising temperature inside the housing and this may lead to miss-readings in the TEMPERATURE and humidity –> For me this won’t affect the overall working principle but this would indicate wrong temp and humidity data which is not a big deal in my case –> But for later one the design has to be enhanced to read more accurate data.

How to maintain a stable airflow inside the housing–> This can be achieved by having large holes in the back of the housing and a good hole distribution.

How the coat of the housing would directly affect the reading of the sensors –> when I was doing the research I read about the TVOC a lot as its organic compounds and they where saying its every where , all around (in furniture, carpets, and disinfectants)–> So this chemical I’m going to put on the Wood is going to effect it hardly –> to avoid it I have to put the piece in open air for almost 3 days but mostly it needs more time until these compounds flays away.

How will it be evaluated?

It works and there is online data being monitored.

How do you see yourself?

Alhamdollelah, I see myself as someone deeply committed to continuous learning and growth, through the years I have built a strong foundation in Electronics design aligned with my education career path. Meanwhile, I’m eager to develop my skills in Management and continue my learning and growth in Electronics and design. This combined will help me in my next challenge as a trainer for the next cycle of FAB-Academy.

Nevertheless, my last 6 months as a student in this year’s FAB-Academy cycle have been a transformative learning journey filled with valuable insights and significant challenges to tackle and resolve. I have savored every moment dedicated to achieving my goal of completing it with excellence.
