INTRODUCTION

Introduction
A Water Level Indicator may be defined as a system by which we can get the information
of any water reservoir. Wa-ter level indicator system is quite useful to reduce the wastage
of water from any reservoir, while filling such reservoir.
Water ismost essentialthing on earth .Safe drinking water is essentialto human and other
life forms even though it pro-vides no calories or organic nutriants.
The total amount of water available on Earth has been esti-mated at 1.4 billion cubic
kilometers,enough to cover the planet with a layerof about 3 km. About 95% of the Earth's
water is in the oceans, which is unfit for human consumption.
About 4% is locked in the polar ice caps, and the rest 1% con-stitutes all fresh water found
in rivers, streams and lakes which is suitable for our consumption. A study estimated that
a person in India consumes an average of 135 litres per day.
This consumption would rise by 40% by the year 2025. This signifies the need to
preserve our fresh water resources

1 Capacitor
It is a passive component with two terminals and used to store charges. Capacitors are mad up of
two conductors which are separated by the dielectric medium flows in between. It works when
potential difference applied across the conductors polarize the dipole ions to store the charge in the
dielectric medium.
Fig. Capacitor
2 Light Emitting Diode
Light-emitting diodes are elements for light signalization in electronics. The basic principle
behind the working of LED is electroluminescence. The Light emitting diode should be forward
biased to get the light. In Light emitting diodes, electrons are injected from low work function
cathode to the conduction band of the n-type semiconducting material and holes are injected from
high work function anode to the valence band ot the p-type semiconducting material. When the
electron in the conduction band combines with the hole in the valence band, energy is released. In
case of indirect band gap semicondutors, phonon will be released to conserve of both energy and
momentum. But in case of direct band gap semiconductor, light will be emitted whose
wavelength depends on the band gap of the semiconductor.

3 Transistor
Transistors are three terminal active devices made from different semiconductor materials that can
act as either an insulator or a conductor by the application of a small signal voltage. The
transistor's ability to change between these two states enables it to have two basic functions:
switching or amplification. Then bipolar transistors have the ability to operate within three
different regions:
 Active Region - the transistor operates as an amplifier and IC = β IB
 Saturation - the transistor is fully-ON operating as a switch and IC = Isaturation
 Cut-off - the transistor is "fully-OFF" operating as a switch and IC = 0
4 Diode
•A diode is a 2 lead semiconductor that acts as a one way gate to electron flow.
– Diode allows current to pass in only one direction.
•A pn-junction diode is formed by joining to gether n-type and p-type silicon.
•In practice, as the n-type Si crystal is being grown, the process is abruptly altered to
grow p-type Si crystal. Finally, a glass or plastic coating is placed around the joined
crystal.
•The p-side is called anode and the n-side is called cathode.
•When the anode and cathode of a pn-junction diode are connected to external voltage
such that the potential at anode is higher than the potential at cathode, the diode is said
to be forward biased.
–In a forward-biased diode current is allowed to flow through the device.
•When potential at anode is smaller than the potential at cathode, the diode is said to
be reverse biased. In a reverse-biased diode current is blocked.

5 Voltage Regulator
A voltage regulator is an electronic circuit that provides a stable DC voltage independent of the
load current, temperature and AC line voltage variations. A voltage regulator may use a
simple feed-forward design or may include negative feedback. It may use an electromechanical
mechanism, or electronic components. Depending on the design, it may be used to regulate one or
more AC or DCvoltages.
Electronic voltage regulators are found in devices such as computer power supplies where they
stabilize the DC voltages used by the processor and other elements. In automobile alternators and
central power station generator plants, voltage regulators control the output of the plant. In
an electric power distribution system, voltage regulators may be installed at a substation or
along distribution lines so that all customers receive steady voltage independent of how much
power is drawn from the line.

6 Transformer
A centre-tapped step-down transformer is used to provide a suitable voltage to the full-wave
rectifier. We specifically selected this transformer so that the device could be connected directly to
the wall outlet. Also the centre tapping helps us to generate a positive polarity voltage required for
the circuit. Rating: 230/12 V AC, 50 Hz
6 Alarm
 Water level alarm is a simple project to detect and alarm once the water level in tank
are aquarium reaches at certain level.

7 Watertank
Water storage tanks, also known as cisterns, are primarily used to store water for domestic and
consumptive purposes in households or buildings. Cisterns are typically found in areas where a
potable water source is not available in the community, the area yields low well water capacity, or
the groundwater quality is poor. Cisterns can also be used to store water: a) to supplement a low
yielding private water well b) as an emergency water supply

WORKING PRINCIPLE

20. [18]
WORKING :
The water level alarm circuit is a simple mechanism to detect and indicate the level of water in the
overhead tank and also in the other containers. Nowadays all the house holders/owners are storing
the water in overhead tanks by using the pumps
When the water is stored in the tank, no one can identify the level of water and also, no one can
know when the water tank will fill. Hence there is an over flow of water in the tank, thus there is a
wastage of energy and water.
To resolve this type of problems by using the water level alarm circuit of a transistor it helps and
indicated the level of water in the overhead tanks. The cost of the water level alarm circuit low and
its use full for the overhead water tanks, swimming pull boilers, etc….
The water level alarm circuits are used in the factories, chemical plants, and electrical substations
and also in other liquid storage system.

ADVANTAGE

22. [20]
Advantages of the proposedwaterlevel controller
A. Maintenance
It is an economical system that requires very less maintenance as compared to conventional
system as it has no complicated circuits and delicate mechanisms. This saves the additional
maintenance cost.
B. Cost
The main advantage of the water level controller is it has very low cost than the conventional one
available in markets. For example, some commercial controllers use microcontrollers which alone
costs around Rs.800. Some controllers even have a price range of Rs.2000-Rs. 4000. But for our
system, the components used are less in number and easily available. Hence losses will be less
leading to a better efficiency.
C. Construction
The construction of a water level controller is very simple as it requires only a few components.
The circuit involved is also relatively simpler.
D. Skill Required
Since the system of water level controller is simpler than the ones conventionally available, it can
be easily made at home. The controller can also be easily operated by anyone.

DISADVANTAGE

24. [22]
Disadvantages
 Required a dedicated controller ( human ) .
 There is a need of automatic system to increase the accuracy .

APPLICATION

26. [24]
APPLICATION
 Water level indicator is used in application like storage tanks, boiler, cooler etc to indicate
level of inside water.
 Easily indicate when water level is full in the tank with beep sound .

27. [25]
CONCLUSION

28. [26]
Conclusion
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 over head tank. A connection runs under to the underground tank to check
the availability of water in that tank before operation the pump and the pump operates only
automatic water level controller can be used in Hotels, Factories etc.
