Controlling of light, climate, doors and window shutters and many more which we cancontrol manually in our daily life. Anybody can do controlling of devices. But here the thing iscontrolling devices is restricted to particular persons who are provided with the password. Thepersons 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 thehome. GSM modem is used to communicate and respond to the remote commands and thosecommands 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 smallmodifications.
