Author Ejaz ur Rehman describes a an extremely simple water-level maintainer that keeps the water level between two predefined levels using an LM311.
This design idea explains how to develop a water sensor circuit that can monitor upper and lower water levels.
The XBee can detect the water level by testing for a closed circuit between the two electrodes of any sensor module. The water acts as a sort of switch that closes the circuit.
As the water rises it completes the circuit, illuminating the LED. [Raikut] is conservation minded and built a buzzer circuit which is activated by the LED indicating the highest water level.
