INTRODUCTION
This project mainly focuses on the controlling of home appliances remotely and providing security.
When the user is away from the system ,This system provides ideal solution to the problems faced by home owners in daily life.
Home appliance control system (HACS) is based on Bluetooth technology and remotely controlled solution for automation of home has been introduced.

BLUETOOTH
Bluetooth is a wireless technology designed as a short range, low power connectivity solution for small peripheral, portable, and electronic devices like mobile phones, printer, keyboards etc.
Bluetooth is now days a major technology for Adhoc networks. It can also be used in “infrastructure based” wireless communication system.
Bluetooth uses 2.4 GHz unlicensed radio frequency for communication
HC-05 Bluetooth Module
Bluetooth Dongle
Bluetooth Block Diagram
Specifications of Bluetooth
Operates in the 2.4 GHZ band which is globally available
It has 79 channels
Hardware encryption/decryption
Can support up to 8 devices in a piconet
Omni-directional, non line of sight transmission through walls
10m to 100m range
Supports both slave and master modes.
1mW power
Extended range with external power amplifier (100 meters)
Liquid crystal display
LCD displays utilize two sheets of polarizing material with a liquid crystal solution between them.
By carefully controlling where and what wavelength (color) of light is allowed to pass, the LCD monitor is able to display images.
MAX 232
It is used for serial communication
The RS232 cables are generally referred to as DB-9 connector.
RS-232 Voltage levels
+3 to +25 volts to signify a "Space" (Logic0)
-3 to -25 volts for a "Mark" (logic 1).
RELAY (SPDT) A relay is an electrically operated switch.
Relays are used where it is necessary to control a circuit by a low-power signal.
Relays protect electrical circuits from overload or faults.
