I live in California, where wine is a USD$2 billion per year industry. A friend is a winemaker. Winemakers like to know the temperature, PH, and BRIX (sugar concentration) of their grape juice while it is fermenting as this tells them when to take action, like stopping fermentaiton. To get this information, they have to drive to the tanks which are often far away from home. So they don’t do this as often as they might, and don’t have the data they could to apply the most scientific method to their product.
Are there any fez-compatible sensors for PH or (esoteric, I know) sugar concentrations or other liquid characteristics?
