RFID CONCEPT BASED PAID CAR PARKING
ABSTRACT
RFID based car
parking uses a microcontroller along with sensing circuits monitoring entry and
exit of cars. The car owners are allowed an entry only when their RFID card is
swiped .The amount in the card automatically gets reduced with a display
indication besides indicating the available number of parking. For loading the
amount 2 push buttons are used SW1 for Rs500 and SW2 for 300.Example is shown
for 2 cards but it can be extended to many numbers. An H-bridge arrangement
operates the entry and exit boom motors operating clockwise and anticlockwise for
opening and closing. A buzzer sound comes while the card is swiped. Upon every
entry of a car the parking availability gets reduced by one number while every
exit the number increases. A standard power supply is used. A seven segment
display displays the status. A switch is used in place of RFID for minimizing
the project cost.
