JFBrew is a DIY temperature controller for a beer fermentation chamber.
It regulates the temperature inside the chamber (a modifier fridge, for example) so that the temperature of the wort (fermenting beer) is stable and controlled.
It uses 3 temperature sensors (beer, fridge and ambiant) and 2 relays (cooler and heater). The brain of JFBrew is a M5Stack board, based on the ESP32 processor.
