Abstract

Radio Frequency Identification (RFID) is used for identification of object
since World War II, when English airplanes are distinguished with Germans’ by using
the technology. Presently, RFID application is used widely in control inventory,
pharmaceutical, medical field and manufacturing lines. The capability of RFID has
evolved from passive to active tags. Active RFID tag is powered by a rechargeable
battery which is not efficient since the battery need to be frequently charge and
replace. This report proposed an alternative power generator charger for the tag to
increase the battery efficiency. Photovoltaic cell is used as energy harvester to absorb
ambient light energy and convert it to electrical energy. The power generated is
directly use to charge a battery continuously under ambient light. LTC3105 DC/DC
and LT1073 Step up converter is experimented to boost the voltage and current from
battery cell in order to produce an output of 3.3V 40mA as minimum requirement to
power RFID Tag. The charging battery is capable to power RFID tag without being
charge frequently. This project comprises the theory of power and energy,
communication system and microelectronics. Mono-crystalline type of PV cell are
used as the cell have high efficiency. Risk and contingency while doing this project is
discussed and recommendation is made to counter the problem.
