ABSTRACT:
RFID is an acronym
for Radio Frequency Identification. This project is a standalone for detecting
the missing tags in RFID system using AT89S52 microcontroller. This project is
useful in all applications where more than two tags are there. RFID is
increasingly used with biometric technologies for security. Primarily, the two
main components involved in a Radio Frequency Identification system are the
Transponder (tags that are attached to the object) and the Interrogator (RFID
reader). Communication between the RFID reader and tags occurs wirelessly and
generally doesn’t require a line of sight between the devices.
RFID tags are
categorized as either active or passive. This project uses passive tags.
Read-only tags are typically passive and are programmed with a unique set of
data (usually 32 to 128 bits) that cannot be modified. The reader has three
main functions: energizing, demodulating and decoding. The antenna emits radio
signals to activate the tag and to read and write data to it.
This
Project helps the hospitals to maintain exact patient data and it can be easily
recognized when ever the patient revisits the hospital. Here we are using
AT89S52 controller as a control unit and 16x2 LCD is used to display the
status. EEPROM is used to store the data.
This project
uses regulated 5v, 750mA power supply. 7805, a three terminal voltage regulator
is used for voltage regulation. Bridge type full wave rectifier is used to
rectify the ac output of secondary of 230/12v step down transformer. The RFID
module requires a separate +5v power supply.
