NTRODUCTION




Electricity

is

the

driving

force

behind

the

development

of

any

country
.

With

the

rapid

increase

in

residential,

commercial,

and

industrial

consumers

of

electricity

throughout

the

world,

it

has

now

become

imperative

for

utilities

companies

to

devise

better,

non
-
intrusive,

Environmentally

-

safe

techniques

of

gauging

utilities’

consumption

so

that

correct

bills

can

be

generated

and

invoiced
.



Nowadays,

Wireless

communication

has

become

ubiquitous,

hence

we

have

tried

to

make

a

system

to

read

energy

meters

with

less

human

efforts

using

wireless

technology
.


Wireless Energy Meter Reading System

O
BJECTIVE


In

India,

large

number

of

employees

are

hired

to

read

meter
.

Using

this

system

very

less

human

effort

will

be

needed

to

read

meters
.


Meter

can

be

read

from

a

far

distance

from

the

consumer’s

place
.



There

some

people

don’t

like

unknown

person

entering

their

homes,

this

dissatisfaction

can

be

solved

by

using

this

system
.

ORKING


In

this

project

we

are

going

to

measure

energy

meter

reading

through

wireless

technology
.





In

the

receiver

unit

identification

number

of

all

energy

meter

are

saved
.

Then

unit

sends

the

signal

for

reading

purpose
.

In

the

receiver

section

there

is

one

computer,

one

keyboard

and

one

wireless

card

with

antenna
.





Transmitter

section

contain

microcontroller
.

When

this

unit

receives

the

signal

from

master

unit

then

it

will

connect

with

the

master

unit

wirelessly
.



Wireless Energy Meter Reading System


Then

master

unit

ask

for

meter

reading
.

At

that

time

meter

reading

are

also

displayed

on

LCD

display

at

meter

side
.

Microcontroller

sends

the

data

to

the

master

section
.




We

can

see

the

real

time

operation

because

the

same

data

will

be

received

by

the

master

side
.

So

we

can

measure

the

meter

reading

fast

and

accurately
.

ONCLUSION


As

a

part

of

curriculum

in

semester
-
8
,

we

studied

interfacing

of

wireless

card

cc
2500
,

its

working

and

application

in

wireless

energy

meter

reading

system
.


We

have

enhanced

our

programming

skills

by

interfacing

LCD,

Wireless

Card

with

AT
89
S
51

in

KEIL

(simulator)

and

tested

on

Flash

Magic
.


The

hardware

could

also

be

interfaced

with

the

personal

computer

and

result

could

be

stored

in

the

central

server

and

its

backup

could

be

taken

on

the

other

backend

servers
.
