This project monitors the water level of the tank and automatically switches on the pump motor when ever tank is empty. When a container or above tank is full, the motor automatically shuts off. This project's major guiding principle is "water conducts electricity." In this project, a 16*2 LCD displays the water level in the overhead tank. In this system, the water levels are sensed by a group of 4 wires that are positioned at various water levels. The outputs from these wires are used by the controller to display the water level and operate the pump motor.
