As a computer nerd and home brewer I’m trying to solve this question: can I monitor de fermentation of my beer from my computer/smartphone?

You know your beer is ready for the next step of the process when the yeast stop working on your worth. There are several ways to estimate this:

1. Specific gravity of the worth. Measure with a densimeter. More info here: https://www.craftbeer.com/craft-beer-muses/defining-gravity
   2)CO2 output. Yeast eat the sugar of the worth and produce CO2 and ethanol.
   3)Ethanol saturation is the fermenter
2. Capacitance of the worth. The wort is basically a sugar solution that get almost all its sugar removed during the fermentation, thus the capacitance of the solution will change.

I will be trying different aprachs to the above ideas and I’m open to your suggestions.

I’m currently experimenting with the capacitive sensor.
