V diplomski nalogi opisujemo nadzorno enoto, ki bo vinarjem prihranila čas pri pretakanju mošta ali vina. Nadzorna enota je na eni strani sestavljena iz elektro omarice in dveh stikal –pretočnega stikala za merjejnje količine tekočine in nivojskega stikala za nadziranje vklopa in izklopa črpalke. Oboje komunicira preko kabla s platformo Arduino. Na drugi strani preko bluetooth HC-06 modula pošiljamo odčitane podatke s senzorjev na aplikacijo na telefonu, kjer lahko spremljamo količino tekočine v cisternah. Nadzorna enota je splošen model in ne velja samo za črpalko, ki smo jo uporabili pri projektu. Važno je le, da je črpalka enofazna.The graduation thesis describes a control unit that will save time for wine producers when pumping must (a wine making term which means unfermented grapes, in nonprofessional’s terms), or wine. On the one hand, the control unit is composed of an electrical box and two switches. First, a liquid flow switch for measuring the liquid level and the second, a level switch for controlling the turning on and off of the pump. Both switches communicate via cable with the Arduino platform. On the other hand, bluetooth HC-06 module sends data readings from switches into the app on the phone, where the amount of liquid in the tank is monitored. The control unit is a generic model and does not apply only to the pump, which was used in the project. It is also, of utmost importance that the pump is single-phased
