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.
