Abstract:
In
this present era everything is Automized right from home to industrial area. A home automation system
integrates electrical devices in a house with each other, as this project
better suit for the physically challenged people .In order to do the
regular activities without having others help. The most common thing that they need
to do are switching ON/ OFF the loads without much human involvement wherever
they are required by using user defined voice commands to switch ON/OFF
different electrical devices.
The
theme of this project is to control different devices by giving voice commands.
One such implementation is home Automation using speech Recognition. By giving
different commands various appliances can be controlled automatically. If voice
command is received successfully by corresponding device an acknowledge will be
coming in the form of beep sound from buzzer. In this way activation of buzzer
depends on the voice command received by particular device. The project is
built around AT89S52 microcontroller .Voice Recognition module is interfaced
with microcontroller to drive the load.
This
project uses regulated 5V, 1A power supply. 7805 three terminal voltage
regulator is used for voltage regulation. Bridge type full wave rectifier is
used to rectify the ac output of secondary of 230/12V step down transformer.
