Home Automation Using Android project mainly aims at controlling electrical loads with the help of android application. The electrical loads are controlled based on Bluetooth input signal. The android device sends the input signal. It becomes too tiring to every time manually turn the switches ON/OFF. This proves to be a big problem in case of disabled or handicapped people. This system makes use of an android device which is responsible for sending input signal. 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.
PIC 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 is very beneficial in case of domestic applications and 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 required for PIC microcontroller and other components operation.
