Week 4 FYP I

Title of activity:

Study of Software and Hardware component in details

Objective: 

1. Ensure the component searched is the correct one

2. To know the specification of each of the component

Content/Procedure: 

Below is the component required to build an RFID door system. 

I would like to explain in detail the MAIN component of this project.

RFID Reader (RFID-IDR-232N)

Specification:

RFID-IDR-232N is plug and play RFID reader. It has

been designed with capabilities and features of:

1.   Low cost solution for reading passive RFID transponder tags.

2. Industrial grade casing for better outlook and protection.

3. Integrated RFID reader, LED, power cable and data cable.

4. Every reader has been tested before it being shipped.

5. Fully operation with 5VDC power supply.

6. Buzzer as sound indication of activity.

7.  Red and green LED for visual indication of activity.

8. Standard RS232 serial cable (female) ready to plug to desktop PC or Laptop.

9.               USB as power source from desktop PC.

10.           2cm reading range.

11.    0.1s response time.

12.           12bytes of data received include start of heading, RFID ID and       start of text

Passive Smart Card 

Read/Only Rfid Transponder Keytag

Transponder Chip	EM4100 Compatible
Frequency:	125Khz
ID Size:	64 bit  Read Only
Encoding Scheme:	Manchester Encoding
Material:	PVC
Temperature:	-20°C - +50°C
Dimensions:	85.6 × 54 × 0.86 ( mm )

This Read Only card is pre-programmed with a unique identification.  Passive RFID transponders, which are available with chips and without chips, they have no internal power source therefore require external power to operate. The transponder is powered by an electromagnetic signal that is transmitted from a reader. The signal received will charge an internal capacitor on the transponder, which in turn will then supply the power required to communicate with the reader. 

Active Smart Card

Read/Write Rfid Transponder Keytag

Transponder Chip	T5567
Frequency:	125Khz
Usable data size:	224 bits  R/W    (7 x 32bit )
Encoding Scheme:	Manchester, FSK,PSK,Biphase,NRZ
Material:	ABS
Temperature:	-10°C - +50°C
Dimensions:	85.6 × 54 × 0.86 ( mm )

This Active RFID transponders are self powered and tend to be more expensive than Passive. Having power on board allows the tag to have greater communication distance and usually larger memory capacity. 

Interface LCD (2x16 Character) with PIC16F877A

To use the LCD, we has to solder 16 pin header pin to it. Hence, below is the schematic diagram for it.

 Conclusions:

I could make sure the correct component for in order to complete this project.
