Automatic Water Level Controller

This is an Arduino based automatic water level controller and indicator project. Here, we are going to measure the water level by using help of ultrasonic sensors. The ultrasonic sensors use the principle of echo. When sound waves are transmitted, they after striking any obstacle return. So, by using this principle we can calculate the time of travel for outgoing as well as returning. By calculation we can calculate the distance. Here we use this concept in our project. The motor pump automatically turns ON when the water level is low. Actually there is a lot of drinking water crisis in India and also in other countries. Today we need to preserve water at any cost. In India, we can see many houses as overhead tanks and they keep on overflowing water. It wastes a lot of water as well as electricity. If we do not do anything on this matter than we can face huge scarcity of water. In this project I Am going to implement automatic water level controller so that we no longer have to manually switch ON and OFF the motor. The device automatically monitors the water level and hence triggers the relay which in turn triggers the motor. This helps in reducing wastage of water as well as electricity. This also reduces manpower as we no longer need to operate it manually.
