The system in the project works by taking input values from capacitor as a sensor. The capacitor is placed inside the tank and as the liquid level rises or decreases, the input values from the capacitor change. By calibrating according to user needs, we can set a LOW level, a MID level and a HIGH level. When the level reaches LOW or empty initia…
