Home Automation Using Android
This project helps to control the electrical loads with the help of
android application. The electrical loads are controlled based on
Bluetooth input signal. This input signal is received from the android
device. Many times it becomes too tiring to operate the electrical
switches manually every now and then. This is a big problem especially
in case of aged or handicapped people.
This system solves the issue by interfacing a unit with home appliances
that switches these loads based on the input received from android
device.
The android device may be any android based phone or tab having an
android OS. The app also provides an effective GUI for providing this
functionality.
An 8051 microcontroller is used in this system. The Bluetooth receiver
is interfaced with microcontroller in order to accept the commands and
then react accordingly. It operates the loads through a set of relays
using a relay driver IC. Relays are used between loads and the control
unit.
This system proves to be very beneficial for controlling various
domestic applications and in industrial setups. The power supply setup
of the system contains a step down transformer of 230/12V, used to step
down the voltage to 12VAC. To convert it to DC, a bridge rectifier is
used. In order to remove the ripples, a capacitive filter is used and it
makes use of 7805 voltage regulator to regulate it to +5V that will be
needed for microcontroller and other components operation.
