Neena Mani, Sudheesh T.P, Vinu Joseph,Titto V.D, Shamnas P.S

Water level indicator is widely used in many industries and houses .In this paper a programmed microcontroller is the basic component for the water level indicator. ATmega 32A microcontroller is helps to indicate the level of water or any other conducting liquid. With the help of an lcd display we can see all the level of the water contained in a tank or in any other vessels. A liquid level sensor (transistor circuit) detects the present level of the liquid in the tank in terms of the voltage across transistor and feeds it to the microcontroller and the microcontroller generates a corresponding output text which in then displayed in the LCD. If the water level is full, then the circuits beeps through the buzzer notifying that the water level is full.
