ABSTRACT

The strategy developed to make power available to promote

the energy efficiency and itsconservation at least cost option.

So new technologies like INTELLIGENT ENERGY SAVINGSYSTEMS are introduced.

An LDR checks the intensity of the light.

The central embedded controller controls the input.

NEED FOR ENERGY CONSERVATION

Energy Conservation is frugal and economically smart.

It improves local economy and reduces higher energy rates.

To control the wastage of power effectively, energy

conservation techniques should be implemented.

It is not only usable in future but also provides flexibility to

adapt and extend.

EMBEDDED SYSTEMS

An embedded system is a special-purpose computer system

designed to perform a dedicated function.

Embedded systems run from simple, with a single

microcontroller chip to very complex with multiple peripherals

and networks mounted inside a chassis or enclosure.

Embedded systems are often mass-produced, benefiting from

economies of scale.

POWER SUPPLY

Itsa simple source of reliable ,stable, low voltage power for

the microcontroller and associated circuitry.

A step down transformer of 230Vto 12V is used.

Recommended specifications for a small project, use a 12V

DC, plug-pack supplying a 3-terminal voltage regulator such

as a IC78L05 or 7805.

The power requirement is that the microcontroller requires

5volts DC

MICROCONTROLLER

The microcontroller is the ATMEL series AVR microcontroller

ATMEGA8.

All the external hardware is interfaced to the I/O ports of the

ATMEGA8.

The power supply is 5V DC extracted from the step-down

transformer of 230V AC supply using IC7805.

The external hardware devices interfaced are LDR, PC and

power supply.

LDR

The resistance of the Light Dependent Resistor

decreases with increasing incident light intensity.

It checks the intensity of the light and switches the

bulbs.

RELAY

It is a mechanical switch between two different

voltages.

These switches are widely used in many applicationsbecause of their simplicity, long life and reliability.

These are used to control and regulate thegeneration and distribution of power.

SOFTWARE

The code written for INTELLIGENT ENERGY SAVING

SYSTEMS is in EmbeddedC language.

It is dumped into the ATMEGA8 and is compiled using AVR

STUDIO.

The output generated is displayed on the HyperTerminal

window.

This Software allows for

Time plotting performance precise calculations

CONCLUSION

In this experimental setup, Light intensity can be

controlled using LDR condition. So power consumption

is reduced.

By incorporating this setup, we can expect more power

conservation which may turn inevitable in future.

It ultimately preserves the nationswealth.

FUTURE SCOPE

This project can be extended to various application

areas.

This project is not only applicable for lights but also

other electronic appliances by using IR Sensors.

This can be developed with wireless network using

different sensors in different places.
