Password operated device Control using mobile communicationABSTRACT
AIM:
The main objective of this project is we are going to develop an embedded system, which will
control all the devices with command (password) from a Remote device (our mobile) through GSM
communication.
IMPLEMENTATION:
This project is implemented on 8051 based At89s52 developed board interfaced with GSM
modem, relay of connecting the devices, LCD for displaying the data.

Controlling of light, climate, doors and window shutters and many more which we can control
manually in our daily life. Anybody can do controlling of devices. But here the thing is controlling devices
is restricted to particular persons who are provided with the password. The persons who know the
password only can control the devices by sending password as message.
In this project we are using at89s52 microcontroller for controlling the equipments in the home.
GSM modem is used to communicate and respond to the remote commands and those commands are
sent to the the micro controller via RS 232 communication means MAX232 chip.
This automation system can also be used for industrial applications with small modifications.
SOFTWARE:
Embedded ‘C’
RIDE to write code
ISP to burn the chip
HARDWARE:
At89s52 based our own developed board
Power Supply
GSM module
RELAY
ADVANTAGES: Low cost, automated operation, Low Power consumption.
