Can this device be used with motors that use a Variable Frequency Drive (VFD)?

Thanks! Looks like it miiight be possible to estimate Chlorophyll contents? Though the paper did not have so much experiments/data on that part...

I am interested in using this to detect adulteration of oils. There is various research that seem to indicate this is possible using visible-light spectroscopy. For example, www.mdpi.com/2304-8158/14...
Have not found any open data though =/

Let me know if you are interested in doing some on-device analysis and/or machine learning around this. I maintain the github.com/emlearn/emle... ML/DSP library, and would love to help out

Really nice! I hope AS7343 breakout comes soon, that would be a nice upgrade. I have asked in Adafruit Discord about it. But if you that have an active project email them, it might help more!

Looks a bit like a flute!
