The project is designed to operate
electrical loads using an Android application device. The system
operates electrical loads depending on the data transmitted from the
Android application device. Operating conventional wall switches is
difficult for elderly or physically handicapped people. This proposed
system solves the problem by integrating house hold appliances to a
control unit that can be operated by an Android smart-phone/Tablet etc.
Remote operation is achieved by any smart-phone/Tablet etc., with Android OS, upon a GUI (Graphical User Interface) based touch screen operation, interfaced to the microcontroller of 8051 family. The program on the microcontroller serially communicates with Bluetooth device to generate respective output based on the input data (sent from Android application device) to operate a set of relays through a relay driver IC. The loads are interfaced to the control unit through the relays. The system can be used in existing domestic area for either operating the loads through conventional switches.
The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.
