IR based 8 channel Remote control using AT89S51

PROJECT TYPE

Microcontroller(AT89C51)hardware design with software development (Device Driver).

 PROJECT DESCRIPTION

This Project “INFRARED REMOTE SWITCH USING MICROCONTROLLER” is used to switch on/off the Home Appliances by using a standard Remote control. The system is used to switch on/off upto six electrical devices. All the above processes are controlled by the 8 bit Microcontroller AT89C2051. 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 10 meters. The system works on Phillips RC5 format. 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.
