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.

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

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.

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.
