Introduction



The

main

aim

project

is

to

improve

the

needs

by

providing

the

equipment

in

the

home

or

industries

we

can

control

the

devices

by

ON

and

OFF

from

any

part

of

the

world

with

Micro Controller(AT89S51) contd..


Microcontrollers are like single chip computers
that are often embedded in to other systems to
function as processing or controlling unit.


They are useful to communicate with other
devices such as displays, sensors, buzzers to
process input to a set of actions.


AT89S52 controller is selected because of inbuilt
ISP (in system programmer) and in order to fulfill
our applications

Light Emitting Diodes(LEDs)

Apply mobile connections to both voice and DTMF
ICs


Connect devices to control to the port 3 pins of
AT89S51 MC


Reset the microcontroller with RST pin of AT89S51
MC

Applications


The ability to control lighting & household appliances


Easy controlling action of machines in an industry


Device controlling in Colleges and Schools


Monitoring of domestic appliances, home security and
energy management


Easy to handle in office buildings, shopping malls and
luxury homes


Advantages


Easy interaction to the users


Less cost and easy to install


Easy to maintain


Remote based controlling of devices in home



Communication to our devices from all parts of the
World


Secure in critical applications


Conclusion



Finally

we

conclude

this

system

that

would

help

for

the

good

interaction

of

user

with

the

heard

voice

(in

mobile)

and

responding

to

it

as

per

his

need

so

that

the

user

can

automated

the

devices

in

homes,

industries
.


Future scope


SMS based system


Helpful in low signaling areas


As the number of devices increases delay increases and cost of
call also increases


Noise and disturbance not occurred by sending SMS
