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 mobile
Literature Survey GSM Mobile PhoneMini ControllerIR version of Mini controllerMini TimerBy Cybernetic concept
Hardware RequirementsMicro controller (AT89S51)Light Emitting Diodes(LEDs)Power supply
Micro Controller(AT89S51)Features:

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)Operation of a LED

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
AdvantagesEasy interaction to the usersLess cost and easy to install Easy to maintainRemote based controlling of devices in home Communication to our devices from all parts of the
WorldSecure 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 scopeSMS based system
Helpful in low signaling areasAs the number of devices increases delay
increases and cost of call also increasesNoise and disturbance not occurred by
sending SMS
