INTRODUCTION
The project is regarding the “infra red detection based car parking system” & is very useful technology in automation of such systems in Malls/Buildings.
In this type of system, as the vehicle reaches the entry of the parking lot, the sensors on the door detect the arrival of the vehicle & will show the nearest vacant parking slot available on the LCD at the door. Similarly there will be IR sensors on the parking lot, which will which will detect the arrival & departure of the vehicle in the lot.
As the vehicle arrives in the lot the sensors will detect the heat & will mark the empty lot as filled in the data base & vice versa.

Hardware description
Major circuit components consist of:
1. Micro controller
2. LCD
3. HT12D-12E
4. RF Transmitter-Receive module
1. Micro controller
The PIC16F887 is a well known product by Microchip. It features all the components which modern microcontrollers normally have. For its low price, wide range of application, high quality and easy availability, it is an ideal solution in applications such as the control of different processes in industry, machine control devices, measurement of different values etc. Some of its main features are listed below.
THE PIC16F887 BASIC FEATURES
• RISC architecture
o Only 35 instructions to learn
o All single-cycle instructions except branches
• Operating frequency 0-20 MHz
• Precision internal oscillator
o Factory calibrated
o Software selectable frequency range of 8MHz to 31KHz
• Power supply voltage 2.0-5.5V
o Consumption: 220uA (2.0V, 4MHz), 11uA (2.0 V, 32 KHz) 50nA (stand-by mode)
• Power-Saving Sleep Mode
• Brown-out Reset (BOR) with software control option
• 35 input/output pins
o High current source/sink for direct LED drive
o software and individually programmable pull-up resistor
o Interrupt-on-Change pin
• 8K ROM memory in FLASH technology
o Chip can be reprogrammed up to 100.000 times
• In-Circuit Serial Programming Option
o Chip can be programmed even embedded in the target device
• 256 bytes EEPROM memory
o Data can be written more than 1.000.000 times
• 368 bytes RAM memory
• A/D converter:
o 14-channels
o 10-bit resolution
• 3 independent timers/counters
• Watch-dog timer
• Analogue comparator module with
o Two analogue comparators
o Fixed voltage reference (0.6V)
o Programmable on-chip voltage reference
• PWM output steering control
• Enhanced USART module
o Supports RS-485, RS-232 and LIN2.0
o Auto-Baud Detect
• Master Synchronous Serial Port (MSSP)
o supports SPI and I2C mode
PIN OUT DESCRIPTION
Most pins of the PIC16F887 microcontroller are multi-functional as seen in figure above. For example, designator RA3/AN3/Vref+/C1IN+ for the fifth pin of the microcontroller indicates that it has the following functions:
• RA3 Port A third digital input/output
• AN3 Third analog input
• Vref+ Positive voltage reference
• C1IN+ Comparator C1 positive input
Such pin functionality is very useful as it makes the microcontroller package more compact without affecting its operation.
