![](https://www.simplecircuitdiagram.com/wp-content/uploads/2010/10/Optocoupler-540x198.gif)
This water level sensor (detector) circuit uses a standard NAND logic gate to produce oscillation and to detect the water level. Oscillation is included inside this circuit to provide alternating current (AC) source for probe electrodes, to achieve a corrosion free operation. With AC source, the process of electrolysis is done in both direction, neutralizing the process of ionic transfer […]
