Week 1.1: My possible final project

Principles and Practices, Presentations, Introductions





I decided to make a DIY KIT to detect the presence of CO2 and avoid its terrible consequences. This is because while I was thinking about what my final project would be, the government of Peru was evaluating the return to face-to-face classes and the companies are returning to "normal." So in the middle of this adventure called Academy, I found that I could contribute to the reintegration of people into shared environments, but safely, avoiding CO2 and possibly the spread of COVID19.




I have thought about what elements I will use and this is a first idea of what is necessary, I will be updating this list if I add more components.

  1. LED light strip.
  2. Arduino ONE.
  3. CO2 detection sensor.
  4. 5V fans.
  5. Case printed in 3D.
  6. Switch.
  7. 5V charger.



First I will model and then I will use 3D printing to make the cloud-shaped case, it will have lateral spaces to install the inlet and outlet fans, in the center it will have a space to adhere the LED light strip. I will build based on Arduino and make the connections. So when we turn it on we will suck in air from the environment and this will be processed by the CO2 sensor, thus indicating what level we are at and under this data, it will turn blue in the best case (350 ppm ~ 800 ppm) and red color at worst (1000ppm ~ 5000ppm). Under this first notice of the degree of presence of CO2 in the place where I am, I must act by opening the windows for better air circulation or reduce the number of people.



The function of this product is to evaluate a gaseous enemy that is not toxic or flammable, but exposure to high concentrations can be life-threatening. I am referring to CO2, which is an odorless and colorless gas, which is why the main function of this product is to indicate and alarm people who are within this environment, if the levels of CO2 in the environment are tolerable. or harmful.

It will mainly be used by all the people who work in shared spaces, it can be a meeting room or a coworking space, classrooms, laboratories or any other place where there are a larger number of people.
