This workflow preprocesses and visualizes sensor data for anomaly detection:
- Read FFT preprocessed data files with date, time, FFT frequency, and FFT amplitude
- Standardize the data by binning the frequencies and averaging the data by sensor, frequency bin and date
- Perform timestamp alignment
- Join all files by date
- Visualize the preprocessed data in a line plot, scatter matrix, correlation matrix, autocorrelation matrix, and heatmap
