logging CO2, VOC, temperature, and humidity with an RP2040
This is basically just a fork of @BlitzCityDIY's Disconnected CO2 Data Logger with minor changes to support an additional sensor for logging VOC info.
I modified the 3D case design a bit as well to support the sensor, add a slightly larger USB-C hole for the cable I use, add a hole for the MicroSD card, and adding some ventilation holes as well. Here is my remix on Thingiverse, and the two modified parts on TinkerCAD: sensor-box and sensor-lid.
This was my first time working with RP2040, CircuitPython, and STEMMA QT connectors. It was a very refreshing weekend project compared to some previous electronics projects which required lots of soldering and C++.
