Abstract

This project is proposed to develop a barcode scanner that sends the scanned barcode to the terminal wirelessly. The existing barcode scanner is actually troublesome because it has to be connected to the computer using cable which is very inconvenience. It faces problem like limited area and range at workplace. To solve this problem, a wireless barcode scanner is developed for user convenience. Besides that, this barcode scanner can be use within 20m. This has increase the distance level covered by the existing barcode scanner. The objective of this project are to transfer data wirelessly and display on computer The main component for this project is PIC16F876A.It is used to control the system using 28 pin. The wireless barcode scanner uses RF 315MHz frequency to transmit barcode wirelessly to the receiver and displaying it on the computer through the hyper terminal. The transmitter module of the system is a barcode scanner with serial output connected to PIC16F876A. The processed data at transmitter will be transmitted through RF 315MHz transmitter to RF315MHz receiver. The receiver will receive the data and send it to computer through serial port. The receiver uses PIC16F876A to process data. The output result can be displayed on computer by hyperterrninal.
