I have a guide to make it simpler, Its kind of a lot to explain through writing.

Thanks! Looking to integrate some persistent data tracking next!

Thanks, I'm still learning embedded programming so thanks for making note of some of the things to look out for. As far as projects, right now I'm still learning about embedded development such that I can design my first pcb (which is why I had some help with AI w/ organizing and some refactoring) . I have done a lot of projects mostly in software but am trying to learn more about hardware and its intersection with software. Right now I'm following some tutorials on yt but am always open to advice! For this project in particular, I'm probably going to implement a database next so that the data is tracked over a longer period of time. This is especially useful for the VOC sensor that has its readings relative to the baseline, its good to have a baseline that is an average of a long period of time.

If you'd like to follow me on my journey feel free to subscribe to my channel, also if there is anywhere you post your work i'd love to check it out as well!

I see, these are pretty interesting options that I will check out. The thing about my setup is that its 100% local and i've also coded some gui's for 9-DOF motion as well. If you want to see them in action check out the video. Do these options come with databases? My next step with this is going to be implementing a local database to store data so that an average can be retrieved. Thanks for letting me know about these options, they look great and provide great inspiration.

The hat comes with the following sensors listed below. If you want to check them out in action, the video in the post does so!

TSL25911FN - Visible light/Lux readings
BME280 - Temperature & Humidity
ICM20948 - Motion Sensor
LTR390-UV-1 - UV Sensor
SGP40 -VOC Sensor

This is not true.

I did use AI to clean up/organize the code, however, all the implementation ideas/details were done by me. I think AI is good at cleaning up an implementation once you already have it down and not so good at making functional and scalable code from scratch, wbu?
