Question Air Quality Monitor from 2022 libraries needed

[HPRonhovde]

I just ran across Tom's Air quality monitor from back in 2022. I bought the SDS011 monitor hardware and now I'm trying to get the software up and running. During the install process it is trying to install 3 libraries, python3-dev, libffi-dev, & libssl-dev. The install chokes on trying to install these libraries. I looked on PyPi for them, intending to download them and install from my system but I can not find them there at all. I have set up a virtual environment on the RPI to run this through since the new version of the OS complains about installing libraries on the system copy of Python. If someone is familiar with this 3 year old application I would appreciate some helpful hints. I'm running a RPI 5 with 4 GB memory and 64 GB SD card with the current RPI OS. I could also use some help with Docker as it is past of this package but I have not looked into it yet. TIA.

For the moment three suggestions:

1) Update your post to include full system hardware specs and OS information.

2) What are your specific requirements regarding air quality?

3) Include a link to the 2022 Tom's Air quality monitor being referenced.

More information needed.

I thought I had covered the hardware and OS issue, I'm running a RPI 5 with 4 GB memory and 64 GB SD card with the current RPI OS. The SDS011 is a laser dust sensor designed to measure particulate matter (PM) concentrations in the air. It can detect particles between 0.3 to 10μm in size and provides PM2.5 and PM10 measurements. It connects to the RPI via USB connection
My requirement regarding air quality are few, this is an experiment to see if an air cleaner I am thinking about purchasing actually does what it says. I will run the system for a couple months to collect data then put the air cleaner in the room and see what the differences are. I realize this has no way of telling me what particles are in the room but then this is my first attempt at doing something like this

The idea started when I ran across this web site from one of toms ads on facebook. https://www.tomshardware.com/how-to/raspberry-pi-air-quality-monitor, It appeared simple enough at the outset but is ending up to be much more difficult than I expected since the core software packages he used do not seem to be available anymore, python3-dev, libffi-dev, & libssl-dev.

I'm doing this for my own education and enjoyment. I'm 79 years old and have worked in computers all my life and want to keep my mind and hands busy.

Any other information that I can provide please let me know.

Fair enough - thanks.

Sounds interesting.

Have you attempted to PM or otherwise contact the link's author?

In any case, I will defer to the Raspberry Pi community regarding hardware and software requirements per se.

There may be other more specific ideas and suggestions posted.

Enjoy.

Thanks for the reply and for working on Easter. I'll keep plugging away and eventually learn what I need to know.
