Design Of Automatic Water Level Controlling System

The shortage and wastage of water in multistoried building is a common problem. In many houses there is unnecessary wastage of water due to overflow in Overhead Tanks. To prevent this kind of situations we have designed a system that would automatically pump water from the reservoir to the tank whenever there is less or full water in it. The operation of water level 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.
