ABSTRACT
Purpose of this project is to control our domestic water pump set with the help of a digital logic circuit. It automatically fill our water tank and we doesn’t bother about to turn ON and OFF the pump set.
The circuit is build around a simple flip-flop, which automatically set and reset with respect to the water level present in the water tank. Two probes are dipped in the tank (one is on the top side and other is at bottom) to check the presence of water and these probes are the input to the digital logic circuit.
It also contains some protection mechanism in order to protect the motor from ‘Dry-run conditions’. For this purpose we are dipping a probe in the water source (Well, Ponds, etc.) and the circuit detect the availability of water in the source, when there is no water in the source, the whole system will be shut down otherwise the motor may burn.
Another facility of this system is that it can identify the purity of water. If the content of mud in the tank increases, circuit not only indicates it but also turn OFF the motor.
Also to know the amount of water in the tank, we are using a ‘Numeric Water Level Display Circuit’ which indicates the amount of water numerically.

INTRODUCTION
1.1 Problem Definition
The present project is about providing automation in the switching of water pump set. In additional to this the project also includes the Water level indicating system and purity checking facility. This project will definitely be useful in households.
1.2 scope of study
This project is developed in order to provide the existing method in the switching of water pump set much more better this also helps to detect the mud in the water and informs the user accordingly
1.3 Project motivation
This project is developed from the thought of getting automation in filling the water tank this will helps to consume time and also the mud detection enhances the advantages of this project.
