Project given is aims to implement the design of data acquisition system and
microcontroller into RFID system. In this project, the analog signal associated
with the ID of patient is acquired and then passed to 8051 Microcontroller to be
processed into useful information for medical application. To achieve this target,
Analog-to-Digital Converter ( ADC ) is used to convert the acquired ID signal that is in
analogue form into an appropriate form that can be processed by 8051 Microcontroller.
The ID of patient will be shown on the screen of PC as result. Next, Digital-to-Analog
Converter ( DAC ) is used to generate an analog signal from the binary data stored in
memory of 8051 Microcontroller. The purpose of generate this analog signal is to show
out and verify that the analog signal is the analog ID signal which represents the ID of
patient. This analog ID signal which generated by DAC will displayed on oscilloscope.
Other than that, if the analog signal used to represent the ID of patient is not correctly
represents the 8 bits ID, the ID of patient cannot be displayed and user is required to
execute again the 8051 program. The four forms of 8 bits ID of patient that this project
capable to display are 00000000, 11111111, 01010101 and 10101010. As conclusion, the
objective of this project is said to achieved if the ID of patient can be displayed on the
screen of PC correctly and the analog ID signal can shown on oscilloscope correctly as
well. In future project, one may consider to design variety forms of ID of patient.
