Now a day's every system is automated in order to face new challenges in the present day situation. Automated systems have less manual operations, so that the flexibility, reliabilities are high and accurate. Hence every field prefers automated control systems. Especially in the field of electronics automated systems are doing better performance.Probably the most useful thing to know about the global system for mobile communication is that it is an international standard. If you travel in parts of world, GSM is only type of cellular service available. Instead of analog services, GSM was developed as a digital system using TDMA technology.The goal of the project is to develop a system, which uses Mobile technology that keeps control of the various units of the home appliances, which executes with respect to the signal sent by the mobile.For utilization of appliances the new concept has been thought to manage them remotely by using GSM, which enables the user to remotely control switching of domestic appliances. Just by dialing keypad of remote telephone, from where we are calling we can perform ON / OFF operation of the appliances.

Overview In this project we are going to control general home appliances based on the mobile communication. The idea behind this particular work is to give user the full flexibility to control the appliances from remote distances when there is a busy schedule concerned to his daily routine.
Motivation The motivation is to facilitate the users to automate their homes having ubiquitous access. Thesystem provides availability due to development of a low cost system. The home appliances con-trol system with an affordable cost was thought to be built that should be mobile providing re-mote access to the appliances and allowing home security.
Problem Statement One of the limitations about this is non availability of power because the power system makes use of power supply from Power Holding Company of Nigeria (PHCN). Though this is a major problem but with thought about alternative source of power, it is a problem that will soon be a by-gone. Also another limitation noticed in the above work is the failure of network or busy network which will make the phone embedded in the system not to be available when called.
Objective The objective of this project is to develop a device that allows for a user to remotely control and monitor multiple home/office appliances using a cellular phone. This system will be a powerful and flexible tool that will offer this service at any time, and from anywhere with the constraints of the technologies being applied. Possible target appliances include (but are not limited to) climate control system, security systems, lights; anything with an electrical interface. The proposed approach for designing this system is to implement a

microcontroller-based control module that receives its instructions and command from a cellular phone over the GSM network. The microcontroller then will carry out the issued commands and then communicate the status of a given appliance or device back to the cellular phone.
Scope The system specification shows the description of the function and the performance of system and the user. The scope of our project “GSM Based control system” is immense. The future implications of the project are very great considering the amount of time and resources it saves. The project we have undertaken can be used as a reference or as a base for realizing a scheme to be implemented in other projects of greater level such as weather forecasting, temperature updates, device synchronization, etc. The project itself can be modified to achieve a complete Home Automation system which will then create a platform for the user to interface between himself and the household
Expected outcome The following is a list of expected outcome and other deliverables.

Literature Review
The first machines to be operated by remote control
were used mainly for military purposes. Radio-controlled motorboats,
developed by the German navy, were used to ram enemy ships in WWI.

Radio controlled bombs and other remote control weapons were used in
WWII. Once the wars were over, United States scientists experimented to
find nonmilitary uses for the remote control. In the late 1940′s automatic
garage door openers were invented, and in the 1950′s the first TV remote
controls were used. Zenith began playing around with the idea of a TV
remote control in the early 1950′s. They developed one in 1952 called
“Lazy Bones,” which was a long cable that was attached to the TV set.
Pushing buttons on the remote activated a motor that would rotate the
tuner in the set. This type of remote wasn’t popular for long considering
that, at the time, there were very few channels to choose from.
In 1955, the Flashomatic was invented. A flashlight was shined toward light
sensitive cells in each of the four corners of the TV. Each corner had a
different function. They turned the TV on and off, changed the channel, and
controlled the volume. However, people often forgot which corner of the TV
operated which control. Also, if the set was in sunlight, the sun’s rays would
affect the operations of the TV. In 1957 a group of engineers developed the
Zenith “Space Command,” a wireless remote control using ultrasonic
waves. The problem with the ultrasonic control was that clinking metal,
such as dog tags, could affect the TV set. High frequencies sometimes also
made dogs bark. The ultrasonic remote was used for two decades until
engineers discovered a better way to operate TV’s, the infrared remote
control. On the infrared control, each button has it’s own command, and is
sent to the TV set in a series of signals. There is a digital code for each
button, and in the TV there is a tiny sensor called a photo detector that
identifies the infrared beam, and translates the code into a command.
Manufacturers used to only make remote controls that operated one TV
set. However, they’ve recently begun making universal remote controls that
can operate any TV set. Experts predict that someday remote controls will
control almost every device in the home. R.C. Goertz developed a
mechanical manipulator in 1948 to aid in radioactive lab work. Goertz gave

the machine mechanically and geometrically similar “master” and “slave”
parts. The master was the part of the machine the Goertz controlled, and
used to send the slave commands. The slave followed the master’s
movements exactly. In 1954 an electrical machine was made to replace
Goertz’s machine, which was operated by cables. Since ’54 better designs
have been developed, but the electric manipulator remains relatively
unchanged to this day.

HOME AUTOMATION SYSTEM
A common definition oF Home Automation is of an “electronic networking technology to integrate devices and appliances so that the entire home can be monitored and controlled centrally as a single machine” (Pragnell et al., 2000). Another term that describe the same technology is “domotics”, which derives from the Latin word domus, meaning home, and informatics, meaning the study of the processes involved in the collection, categorization, and distribution of data. However, since this technology is still very much in flux, other terms are also used in the literature with equivalent meaning, such as: “smart home ”, “smart house”, “digital home” or “electronic home”. Furthermore, note that, although the terms “house” and “home” have a different meaning in the English language, they are often used alike in this context. ( Delgado, et al., 2006) consider the problems with the implementation of home automation systems. Furthermore the possible solutions are devised through various network technologies. Several issues affecting home automation systems such as lack of robustness, compatibility issue and acceptability among the old and disabled people are discussed. (Ciubotaru-Petrescu, et al., 2006) present a design and implementation of SMS based control for monitoring systems. The paper has three modules involving sensing unit for monitoring the complex applications. A processing unit that is microcontroller and a communication module that uses GPRS modem or cell phone via serial port RS-232. The SMS is used for status reporting such as power failure. In their paper, ( Scaradozzi et al,. (2003) view home automation systems as multiple agent

systems (MAS). In the paper home automation system has been proposed that includes home appliances and devices that are controlled and maintained for home management. The major task is to improve performance. In their paper, ( Alkar et al,. 2005), they proposed an Internet Based Wire ess Home Automation System for Multifunctional Devices. This paper proposes a low cost and flexible web-based solution but this system has some limitations such as the range and power failure. Murthy (2008) explores primary health-care management for the rural population. A solution proposes the use of the mobile web-technologies providing the PHC services to the rural population. The system involves the use of SMS and cell phone technology for information management, transactional exchange and personal communication. ( Jawarkar, et al,. 2008) propose remote monitoring through mobile phone involving the use of spoken commands. The spoken commands are generated and sent in the form of text SMS to the control system and then the microcontroller on the basis of SMS takes a decision of a particular task. (Potamitis, et al,.2003) suggest the use of speech to interact remotely with the home appliances to perform a particular action on behalf of the user.

Summary
The extensive capabilities of this system are what make it so interesting. From the convenience of a simple cell phone, a user is able to control and monitor virtually any electrical devices. This makes it possible for users to rest assured that their belongings are secure and that the television and other electrical appliances was not left running when they left the house to just list a few of the many uses of this system. The end product will have a simplistic design making it easy for users to interact with.This will be essential because of the wide range of technical knowledge that homeowners have.
