Microprocessor Based Water Level Controller

Abstract

It is a wonderful project presented in this paper. It avoids the unnecessary overflow of the overhead tank when the motor is running to fill the water to the tank from the underground water. The overhead tank is generally used to supply the water to different parts of the building. This controller is designed using the Microprocessor 8085A and some electronic circuitry. The level of water will be displayed on the seven segment LED display units and accordingly the motor starts running automatically if the level is below desired level and stops the motor if the overhead is filled full.
