Final Project

My initial idea

You can find my initial idea here.

For my code you can follow its construction here

Weekly Summary

Week 2

In week 2 I created the basic pin design that will be used in the breadboard type thingy.

Pin

This pin will be modified so that I can fix the PCB, input devices and other stuff on it.

I also created the breadboard design.

Week 4

In week 4 I started working on the code. We were only supposed to simulate stuff but because the simulation did not want to work I did the real thing. And in the end I got a temperature sensor to work.

Week 5

In week 5 I printed my pin. I did several prints as the first print, the layers was in the wrong direction and the pin broke instantly. Than I tested PETG VS PLA, but I think the size of the pin is too small to really discern a difference between those two plastics.

I also cut the breadboard this week so I could test my pin.

Week 6

Week 6 my biggest concern was to found a pin layout that would allow me to easily use the ESP32 in another board

And there was one in the FabAc library.

Week 8

In week 8 I created a module for fixing my temperature sensor.

I just need to modify my 3D Pin model so they can fit together.

Week 9

week 9

Input devices:

  • SCD30
    • Temperature
    • Humidity
    • CO2
  • SGP30
    • CO2
    • VOC

Noise level measurement is way harder than just plugging in a mic...

Week 10

So this week I played around with the OLED screen.
