During October 2025, Mathieu Jousson enhanced the flipoyo/MOLONARI1D repository by developing three core features focused on sensor data analysis and audio processing. He improved the Jupyter Notebook workflow for real sensor data, refining data loading, processing, and visualization using Python, Pandas, and Matplotlib. Mathieu introduced a frequency analysis module to extract ground properties from temperature signals at various depths, integrating audio playback for deeper insight. He also implemented robust error handling and refactored playback functions for maintainability. Throughout, Mathieu proactively addressed pandas compatibility issues, ensuring future-proof code and comprehensive documentation to support ongoing data analysis and visualization needs.
