This is to certify that Madhuram Khatri of class 12th B
has successfully completed the work of in the year of
2022-23 under the guidance of
my teacher. He has taken proper care and sincerity in the
completion of this project. All the work was related to the
project was done by the candidate himself.
I certified that this project is up to my expectation and as
per the guidelines issued by the school.
CERTIFICATE

ACKNOWLEDGEMENT
I HAVE TAKEN EFFORTS IN THIS PROJECT. HOWEVER, IT WOULD NOT
HAVE BEEN POSSIBLE WITHOUT THE KIND SUPPORT AND HELP OF MANY
INDIVIDUALS.
I WOULD LIKE TO THANK PRINCIPAL SIR, REV. FATHER GEORGE K.K, AND
SCHOOL FOR PROVIDING ME WITH FACILITIES REQUIRED TO DO MY
PROJECT.
I AM HIGHLY INDEBTED TO MY
PHYSICS PRATICAL TEACHER , FOR HIS INVALUABLE GUIDANCE WHICH
HAS SUSTAINED MY EFFORTS IN ALL THE STAGES OF THIS PROJECT
WORK
I WOULD ALSO LIKE TO THANK MY PARENTS FOR THE CONTINUOUS
SUPPORT AND ENCOURAGEMENT

This project provides complete information on the topic "AUTOMATIC
WATER LEVEL INDICATOR "and maximum efforts
have been taken to make the project more
comprehensive and lucid to understand.This
project covers a variety of sub topics like basic
information it's working, day to day uses in life
and different aspects of water level indicator
system. One may notice a perceptible change in
written in an easy dialogue style engaging the
readers constantly and included with more informatics comments. I
assure you to go through this project thoroughly to know a bit more
about Water Level Indicator.
PREFACE

INTRODUCTION
Nowadays everybody has overhead tank at their homes, but the one who
has a tank above knows the kind of problems they face. Water tank
overflow is a common problem which leads to the wastage of water.
Making a simple and handy circuit which will detect the water level and
will raise an alarm upon getting the water tank full on a preset level.
This simple transistor based water level indicator circuit is very useful
to indicate the water levels in a tank. Whenever tank gets filled, we get
alerts on particular levels . Here we have created levels by alarms and
we have added LEDs to indicate full level. When tank gets filled
completely we get beep sound from buzzer. So now we do not have to
worry about overflow and water out anymore.

WORKING OF AUTOMATIC WATER LEVEL INDICATOR
The Sensor Part: It is generally a fixed support inside the tank having
some nuts and bolt with wires coming out.
The Circuit Part: It comprises the brain of the
will get all the information of how much of water
The Power Supply: It is the part where you will be converting the AC
voltage to a regulated voltage of 5V to the Circuit.
The Buzzer Part :It is responsible for bringing up the sound when the
water level fills up in the tank. It will also be having a speaker or a
buzzer to alert.
There are four parts in this project:
module; where in all the various inputs from the
sensors are fed. It is the unit from where you
is in the tank

ADVANTAGES
Easy to operated fast response
Smaller in size
Efficient design eliminates man's work
Low power consumption and reduces wastage.
Conserves Energy
Conserves Water
DISADVANTAGES
Water level controls need to be replaced every 3 years.
The rust, foul and deteriorate
More difficult installation
Most float switches are outdated
No Warranty or Guarantee
Required a dedicated controller (human).
There is a need of automatic system to increase the accuracy.

CONCLUSIONS
This is a simple model water level indicator which can be made at
your home. This project is the solution to help the user to
indicate water level in reservoir or into the water tank that
indicated different levels in an overhead tank. A connection runs
under to the underground tank to check the availability of water
in the tank before operation in the pump and the pump operates
only. Automatic water level controller can be used in Hotels,
Factories, Homes, Apartments Commercial complexes Drainage
etc.
Finally the project has been
successfully implemented and tested.
