My attempt and results

After adding a 3.5mm Audio Jack to the Coqui build we've begun recording waves. Here is a recording of Bezoya bottled water plus an adition of the same water with a teaspoon of salt.

To record the signal we've used a handy audio recorder. It's also possible to record it directly with the computer using the Free Open Source Software Audacity. Follow this instructions to select the input device in Audacity

Questions and next steps

Use a known conductivity solution to use at the begining of each recording. Analize the sprectrum of the signal using Audacity.
