an integrated plan that will make CRAFTBEERPI work well, and now it records these specific gravity data into Google's spreadsheets. Once the liquid gravity meter can be connected to the fermentation controller, the set of automatic fermentation settings will be based on the activity of the yeast directly and more easily, rather than complete the main fermentation within 4 days, you can set the temperature after 24 hours of stable gravity.For some projects
