Stress tests and temperature plots for the Raspberry Pi
There are a million ways to cool down your Raspberry Pi: Small heat sinks, specific cases, and some extreme DIY solutions. stressberry is a package for testing the core temperature under different loads, and it produces nice plots which can easily be compared.
The famous FLIRC case. Thanks to @RichardKav for the measurements!
To run stressberry on your computer, simply install it with
[sudo] apt install stress
pip3 install stressberry --user
and run it with
stressberry-run out.dat
stressberry-plot out.dat -o out.png
(Use MPLBACKEND=Agg stressberry-plot out.dat -o out.png if you're running the script
on the Raspberry Pi itself.)
The run lets the CPU idle for a bit, then stresses it with maximum load for 5 minutes, and lets it cool down afterwards. The entire process takes 10 minutes. The resulting data is displayed to a screen or, if specified, written to a PNG file.
If you'd like to submit your own data for display here, feel free to open an issue and include the data file, a photograph of your setup, and perhaps some further information.
To run the tests, just check out this repository and type
pytest
