LIQUID LEVEL CONTROLLER

Abstract

In this project we aim to save the two most important source of energy for which the present world is facing a scarcity that is water and electricity. For this reason we selected our topic as LIQUID LEVEL CONTROLLER .In this we are using LEDs to indicate different levels of water of upper tank as well as the surge tank .So that before over flow occur the motor can be switched off and thus saving of water and electricity can be done. The level of the water in a field is controlled by this equipment using microcontroller. Main components are 8051 microcontroller, LED, transistor etc.The sensors sense the intensity of water and give indication to the microcontroller. The microcontroller produces the control signals to drive the motor and to glow the corresponding LED. If there is no water then microcontroller gives control signal to start the motor and if there is sufficient water in the field then the microcontroller give control signal to stop the motor.
