I. INTRODUCTION
An institution spends lot of manpower and funds on efficient parking. This system very well reduces the dependency on the above, and makes the parking system automated. The project covers aspects right from checking the legitimacy of the vehicle, to an automatic credit deduction system. With the help of the 8051 microcontroller, we have achieved a smart parking system. Upon entry of a vehicle, the owner must display his/her RFID tag. The RFID number is verified with the database, and the screen displays that the entry is permitted. Two IR sensors have been used, one at the entry gate and one at the exit gate. These help in keeping a count of the vehicles inside the parking lot, and display if the parking lot is full. Additionally, each RFID card is linked with a certain number of credit points. Upon authentication and entry of the vehicle, 100 credit points are deducted. This helps in automation of fee collection. It can be deducted from the salary of the RFID holder. On the entry gate, there are also two recharge options. With the click of a simple switch, the owner can recharge credit points corresponding to his RFID.
II. THEORY
A. 89S52 CHIP
The AT89S52 is a low-power and high performance CMOS 8-bit small scale controller with around 4K bytes of in-framework programmable high-thickness nonvolatile Flash memory. It is good with the business standard 80C51 guideline set and pinout. It gives the standard highlights: 4K bytes of Flash and furthermore 128 bytes of RAM, 32 I/O lines, Watchdog timer, two information pointers, two 16-bit clock/counters, a five-vector two-level interfere with engineering, a full duplex serial port, on-chip oscillator, and clock hardware. It is planned with static logic for task down to zero frequency and backings two programming selectable power sparing modes.

B. 8051 DEVELOPMENT BOARD
The A micro controller is an integrated circuit or a chip with a processor and other help gadgets like program memory, data memory, I/O ports, serial correspondence interface and so forth incorporated together. There are 3 framework inputs, 3 control signs and 4 ports (for outside interfacing). A VCC control supply and ground. XTAL 1 and XTAL 2 are for the framework clock contributions from precious stone clock circuit. RESET input is required to instate small scale controller to default or even wanted esteems and to make another begin. The 3 control signs, EA,PSEN and ALE. These signs known as External Access (EA), Program Store Enable (PSEN), and Address Latch Enable (ALE) are utilized for outside memory interfacing and If there is no necessity of outer memory interfacing at that point, EA stick is pulled high (associated with Vcc) and two others PSEN and ALE are allowed to sit unbothered. There are four ports numbered 0,1,2,3 and called as Port 0, Port 1, Port 2 and Port 3 which are utilized for outer interfacing of gadgets like DAC, ADC, 7 section show, LED and so forth. Each port has 8 I/O lines and they all are bit programmable.

C. Board Programmer
Board should be programed with the goal that the majority of the parts associated with it works as indicated by the guideline gave by programmer.

D. IR Module
An infrared sensor is an electronic gadget which measures the heat of an object and also identifies movement. They recognize just infrared radiation, instead of emitting it known as the passive IR sensor. The producer is an IR LED and the identifier is an IR photodiode which is quite sensitive to IR light of an indistinguishable wavelength from that emitted by the IR LED. At the point when IR light falls on the photodiode, the resistances and these yield voltages, change in extent to the magnitude of the IR light got. This circuit has in it the following parts
• LM358IC2 IR transmitter and receiver pair?
• Resistors of the range of kilo ohms.?
• Variable resistors.?
• LED (Light Emitting Diode).

E. DC motors
A DC motor is a device that converts electrical energy (direct current system) into mechanical energy. The construction of a DC motor contains a current carrying armature which is connected to the DC supply end through commutator segments and brushes. The armature is placed in between north south poles of a permanent or an electromagnet. As direct current is supplied in the armature, a mechanical force acts on it due to electromagnetic effect of the magnet. This helps in the movement of the motor and wheels attached to it.?

F. RFID 125 KHz reader and Tag
This is a low frequency (125 KHz) RFID?Reader With serial Output with range upto 15cms. The RFID Reader is designed specifically for low-frequency (125 kHz) passive tags.Frequency refers to the size of the radio waves used to communicate between the RFID system components. RFID reader reads EM4100 family transponder tags that are brought in proximity to reader and output the unique tag identification number through serial port @9600 bps. The RFID Card Reader from Rhydolabz is designed for low-frequency (125 kHz) passive tags. Frequency refers to the size of the radio waves used to communicate between the RFID system components. RFID (Radio frequency identification) systems use data strings stored inside RFID tags to uniquely identify people or objects when they are scanned by an RFID reader. The distance over which the RFID tag is usable is affected by such things as the tag shape and size, materials being used in the area near the reader, and the orientation of the reader and tag in respect to each other and in their operating environment.

G. 16*2 LCD Screen
A liquid crystal display or a LCD, is a amalgamation of two states of matter, the solid and the liquid. LCD uses a liquid crystal to form visible image which can be used to display numbers or even alphabets. Liquid crystal displays are quite thin technology display screen. It even allow displays to be much thinner when they are compared to CRT. The LCD works on the principle of blocking the light.It consumes less amount of power compared to CRT and LED,low cost and are thinner and also lighter.

V. WORKING
We can divide the circuit working into 2 phases:?
• EntryPhase?
• Exitphase?
At entry gate, the user scans the RFID tag to the scanner. In this, a tag number of RFID card is given to each and every card holder and this card number is matched with the give tag number in the database. When the tag number matches the card number, the system authenticate the vehicle and gate opens and same is displayed on LCD screen. As the vehicle crosses the IR module, the count increases. IR module works in reverse biased manner -when there is no vehicle it won’t be receiving back anything so is not working. As soon as the vehicle crosses the module, the light gets deflected and photodiode receives the light and the circuit is complete. The IR module acts as an interrupt that increases the count every time someone crosses it.
When it comes to the exit gate it again crosses the IR module and the count is decreased.?For this system we have taken 12 parking slots. So if the lot is full, it will display a regret message on the screen of LCD.
Each RFID tag has credit points linked to it. Upon authentication and entry, there will be deduction of 100 credits from the card. At the entry gate, there are two switches provided with a recharge facility. When the credit falls below 500, it is displayed on the screen and the employee can recharge the credit points.
Thus, the system will be updated with the parking lot scenario.And would respond accordingly to the coming guest.

VII. CONCLUSION
The paper examines the significance of utilizing a RFID based
stopping administration framework alongside Infrared sensor(IR). This framework will encourages a quicker client confirmation and thus diminish holding up time and builds the effectiveness of the parking spot.. It limits the exit of a vehicle without installment. It likewise empowers the client to get to the accessibility of the parking spot and will give hold up motion until the point that the space is not accessible for stopping. This paper examines about the opening accessibility subtle elements by utilizing an IR sensor RFID framework and a refreshed intermittently database, Entry point and leave point will be under control by IR sensors and RFID perusers, names and hindrances separately. Work force cost will be decrease
significantly utilizing this innovation.
Smart parking system is thus seen to have many advantages over the conventional parking system. The RFID helps in authentication of the employee, ensuring no stray vehicle enters. The IR sensor at entry and exit points help us to know if the parking lot has any available slots by maintaining a count of the vehicles inside. The credit system with each RFID also helps in automatic fee collection. Overall, the dependency on mankind is reduced drastically, and thus the overall expense in maintaining a parking lot is decreased. ?
