Arduino based Smart Submersible Pump Controller

Nowadays, the drinking water is becomes a big issue. It might very big global problem. As we say that the third world war might be for water. Hence, it is time to think to preserve water. In home based water tank, the one problem is very common to us that the control of water level of overhead tank, as a result the wastage of water is increasing day by day. But we all know water is very precious to us. This problem can be controlled by an electronic circuit consists with some electronic components, that circuit is called ?Arduino based Smart Submersible Pump Controller?. The operation of Arduino based Smart Submersible Pump Controller works upon the fact that water conducts electricity. So water can be used to open or close a circuit. As the water level rises or falls, different circuits in the controller send different signals. These signals are used to switch ON or switch OFF the motor pump as per our requirements.
