ABSTRACTION:

    • 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 8 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 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. 

COMPONENTS REQUIRED:

    • *Microcontroller AT89C2051.
    • *TSOP 1738
    • *Transistor BC547

2051 CONTROLLER:

The 2051 is a 20 pin version of the 8051. It is a low-voltage, high-performance CMOS 8-bit microcomputer with 2K bytes of Flash programmable and erasable read only memory. Atmel manufactures the chip using high-density nonvolatile memory technology. The 2051 and is compatible with the industry-standard MCS-51 instruction set. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel 2051 is a powerful microcontroller. It provides a very flexible, cost-effective solution to many embedded control applications

FEATURES OF 2051:

The 2051 features Compatibility with MCS-51 ™ Products, 2K Bytes of Reprogrammable Flash Memory with 1,000 Write/Erase Cycles. The operating range of the 2051 is 2.7V to 6V....
