Abstract  

This Project INFRARED Based Multi Device Switching Using TV Remote is used to switch on/off the Electrical Gudgets by using a TV Remote control. The system is used to switch on/off up to six electrical devices. All the above processes are controlled by the 8 bit Microcontroller. The Microcontroller receives the Infrared Signal from the receiver and it decodes and switch on/off the appropriate Device. The Range of the system is upto 3 meters.  The project can switch on/off electrical devices of maximum load current of 5Amperes. High power loads can also be connected by changing the Relay. The Microcontroller is used to receive the Infrared signal from the Transmitter, the received signal is processed by the Microcontroller and according to the signal the corresponding device is switched ON/OFF. The IR remote is generally used in home theatres and is based on the principle of using infrared light as the medium of communication. A TV remote basically consists of a set of buttons and a circuit board. Each button is embedded with a black conductive disk which acts as a contact between the buttons and the printed circuit board. The circuit board or the chip consists of a circuitry to sense the connections or detect the button being pressed and produces the signal in Morse code form which is amplified by the transistors and then given to IR LED. The IR LED is connected to end of the circuit board and emits infrared light which is sensed by the sensor placed at the receiver of the TV.
