CHAPTER 1
INTRODUCTION
The rapid development in science and technology has paved its way for sophistication by automation. People now a days, are inclined towards devices that are sophisticated, simpler to use and secure. In this project entitled “Home Appliances Control using Different Controlling Modes “, a prototype is developed which shows how the best utilization of technology can be made in order to secure a home not only from threat but also by ensuring all the safety measures. The project also throws light on the sophistication of the house by monitoring and controlling the devices using RF and VOICE technologies. The main motto of the project is to ensure complete safety and automate all the devices. This is done by interfacing all the devices to a PIC microcontroller”PIC16F84A”. Apart from alerting the user regarding threats a feature is provided where the user can monitor and control all the devices such as tube lights, fans, air conditioners, refrigerators etc. whenever there is a power cut the user is immediately intimated.

A home appliance control system (HACS) is a system which provides various services to remotely operate on home appliances, such as microwave oven, TV, and garage door etc through remote devices such as mobile phone, desktop and palm-top. This project is designed to make home automation easy to control when a user is not at home. The project is designed to allow easy use of a RF and VOICE modes to control appliances in the home. Using a RF and VOICE modes the development of the control system will be carried out. These modes will communicate to control the devices attached to microcontroller modules. When the action has been carried out then a response is sent to the user. The project involves three main areas, research, development\programming, testing and the writing of the report.

The Home appliance control system is controlled by using RF and VOICE modes. It controls various appliances such as a microwave, TV etc. The HACS system receives commands from remote devices that are manipulated by user. The system in turn dispatch commands to respective appliances that will perform the actions. HACS is responsible for keeping track of the states of the devices. If something goes wrong, it will notify the user by sending command back to the remote devices as well as emergency department if necessary. The system administrator of the HACS system has the ability to add a new appliance or delete an existing one. The system administrator has the ability to add a new remote device and configure it with HACS or delete an existing one when it is not used. Also the system administrator can create an account for a new user or delete existing account if it is no longer used.

PREVIOUS TECHNOLOGIES
2.1 INFRARED (IR) BASED HOME APPLIANCES CONTROL

IR extension is a previous proposed system which is implemented over certain range. A control system is being implemented in such a way that. The control system would be designed to control the units at remote location, using web-enabled interface (either GPRS) and remote location would be interfaced to the appliances to the Infrared interface. This idea is extendible to the Bluetooth interface as well instead of Infrared (wherever applicable) but the current paper would be focusing on the Infrared as a remote appliance control.

IR always needs a line of sight and we will need a robust feedback mechanism, to verify the operations, we are not focusing the efforts towards deploying Bluetooth instead of IR is because, practically speaking, most of the home appliances are not Bluetooth enabled today (eg. Refrigerator, TV, Music Player, PC, Heaters etc) and specifically there will be changes required on either ends in case we need to use Bluetooth instead of IR. Hence to us, today, IR looks most suited to be used from applications perspective.

To access the control unit, the user should start with first...
