3. 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.

4. MICRO CONTROLLER
AT89S52
 8K Bytes of In-System Reprogrammable Flash Memory
 256 x 8-bit Internal RAM
 32 Programmable I/O Lines
 Three 16-bit Timer/Counters
 Eight Interrupt Sources
 4.0V to 5.5V Operating Range
 Full Duplex UART Serial Channel
 Interrupt Recovery from Power-down Mode
 Power-off Flag
 Fast Programming Time
 Flexible ISP Programming )

5. 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

6. HC-05 Bluetooth Module
Bluetooth Dongle

7. Bluetooth Block Diagram

8. 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)

9. 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.

10. 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).

11. 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.
