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.

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.

9. Stand Design And Fabrication

Posted April 11, 2024

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.

Let’s Start designing this part

  • I will use Also ONShape to design –> For more Information about the process of designing using ONshape Please refer to this LINK.

  • I will build My design to look rounded as my Main piece so I will go with cylindrical shape.

  • Now I will start a sketch and I will draw a circle with 50 mm diameter.

Sketch circle

  • Then I will Extrude this by 5 mm to work as a base for the entire model.

Extrude Base

  • Then I will sketch the base of the sensor (PM2.5).

PM sensor dimension

I will use this sketch from the Sensor data sheet as a reference.

  • I will have the sensor in the vertical position.

Sensor Dimension

  • Then I will extrude to include the height of the sensor.

Sensor Height

Here I have added 0.5 mm clearance to make sure the sensor will fit but also will be tight so it wont fall if the stand is carried.

  • Then I will extrude remove the back side of the shape to insert and remove the sensor from this side.

Sensor gate

  • NOw I will use the back of the shape to sketch the ventilation of the sensor.

Sensor ventilation

  • THen I will Extrude remove the sketch.

Sensor ventilation extrude remove

  • Then I will sketch and extrude the top of the sensor.

Sensor top sketch

Sensor top sketch extruded

  • Now The Sensor Enclosure Is done and I need to think of a shape that can hold the main housing piece.

I had a lot in mind to sketch but nothing was reliable and make sense to me because as always I want something simple and easy to build.

So I thought of having a half circle that holds the housing, another option was two sticks and holding the piece as a fork. but nothing was enough for my mind to build.

I took a break and then I remembered (Iron man and his glowing heart 🤣) –> So I decided to have the top part to look as a hand and this piece is contained in this hand.

  • Lets build the hand.

  • So I started a sketch on the top of the sensor container piece.

Sketch of the hand

  • Then I will extrude these parts.

Sketch of the hand extruded

Sketch of the hand extruded 2

  • Then I will Sketch a spline on one of the Fingers 🤓 to be then revolved (remove).

Spline Sketch

  • Before I revolve remove the spline I will reduce the height of the big finger 😅.

MAin finger

  • Now I will revolve remove the spline shape.

Revolve remove

Here we go the Stand Is ready NOW.

Design Is DOne

  • Now Lets Fabricate the STand Using the 3D printer.

  • I will use Cura to slice the file.

Slicer settings

Slicer settings

Here I will use 0.2 layer height and 10 % infill but I will use support to handle the 90 degree overhang I have.

Slicer estimation

  • NOw this print will take 6 hours which is a bit long for me.

  • Lets go ahead and print it.

Here We go the Stand Is ready

Alhamdollelah All what I need is now Done and In a perfect condition as I want.
