INTRODUCTION
This
Project
REMOTE
CONTROLLED
SWITCH
BOARD is handlingd to switch on/ send finish the Home Appliances by using a archetype Remote operate on. The system is used to switch on/off up to six electrical devices. All the above processes atomic number 18 controlled by the 8 bit Microcontroller AT89S52. The Microcontroller receives the Infrared Signal from the recipient role and it decodes and switch on/off the appropriate Device. The Range of the system is unto 10 meters. The project can switch on/off electrical devices of maximum load current of 5Amperes. High indicant loads can also be connected by changing the relay race and the devices will come to the original tell apart after the power failure. The Microcontroller is used receive the Infrared portend from the Transmitter, the received maneuver is processed by the Microcontroller and according to the signal the
corresponding device is switched On/off. Any RC5 remote control can be used to control this circuit. The remote we use sends a train of bits (0s and 1s) of some immovable length modulated with a 38 KHz infrared emission signal.
The sequence of bits which the remote sends is decided by a particular
protocol known as RC-5 protocol.
