CELL PHONE BASED DEVICE CONTROL WITH VOICE ACKNOWLEDGEMENT 2013-14 ABSTRACT

Home automation refers to the use of computer and information technology to control home appliances and features (such as windows or lighting). Systems can range from simple remote control of lighting through a complex computer/micro-controller based networks with varying degrees of intelligence and automation. Home automation is adopted for reasons of ease, security and energy efficiency. In modern construction in industrialized nations, most homes have been wired for electrical power, telephones, TV outlets (cable or antenna), and a doorbell. Many household tasks were automated by the development of specialized appliances. For instance, automatic washing machines were developed to reduce the manual labour of cleaning clothes, and water heaters reduced the labour necessary for bathing. Other traditional household tasks, like food preservation and preparation have been automated enlarge extent by moving them into factory settings, with the development of pre-made, pre-packaged foods, and in some countries, such as the United States, increased reliance on commercial food preparation services, such as fast food restaurants. Volume production and the factory setting allows forms of automation that would be impractical or too costly in a home setting. Standardized foods enable possible further automation of handling the food within the home. The use of gaseous or liquid fuels, and later the use of electricity enabled increased automation in heating, reducing the labour necessary to manually refuel heaters and stoves. Development of thermostats allowed more automated control of heating, and later cooling. As the number of controllable devices in the home rises, interconnection and communication becomes a useful and desirable feature. For example, a furnace can send an alert message when it needs cleaning or a refrigerator when it needs service. Rooms will become "intelligent" and will send signals to the controller when someone enters. If no one is supposed to be home and the alarm system is set, the system could call the owner, or the neighbours, or an emergency number. In simple installations, domestics may be as straightforward as turning on the lights when a person enters the room. In advanced installations, rooms can sense not only the presence of a person inside but know who that person is and perhaps set appropriate lighting, temperature, music levels or television channels, taking into account the day of the week, the time of day, and other factors.

MARKETING SURVEY

Shops visited: Jain Electronics, Rajasthan Electronics.Some of the components were not available so need to order it.

Our project Cell Phone Based Electronics Voting machine is designed according to the current need in the market. We conducted a survey in offices, both small and medium scale industries where message communication is required between employees. For this existing technologies used were LAN and internet. Both require bulky and costly installation equipments.

So in order to provide an efficient and cost effective alternative, we designed our project. The initial cost of project is less as well as the subsequent usage charges are minimal. The range of this project kit is 100 meters. The project also provides security as frequency of each kit is set according to the sender at one end and the receiver at the other.

In todays existing market competition is very tough. So to provide a competitive price, mass production of product is required. Publicity and marketing of product is to be done very precisely. The designed product can also be used in colleges and schools to make wireless noticeBoard such that the Head of Department or Principal can update the notice board any time.

The vision of wireless communication supporting information exchange between people or devices is the communication frontier of the next few decades, and much of it already exists in some form. This vision will allow multimedia communication from anywhere in the world using a small handheld device or laptop.
