Project Summary

This project aims in designing a completely automated security access system for domestic and industrial applications. Security is bigger concern for an individual or a firm. Recognizing the need of security we developed an automated security access with user friendly access.

Automation is the most frequent spelled term in the field of electronics. The hunger for automation brought many revolutions in the existing technologies. One among the technologies which had greater developments in RF communications. The result of this is the RFID cards which transmit a unique identification number. This number transmitted by the RFID can be read with the help of a RF reader. 

There has been rising demand for secure system that must be dependable and quick respond for the industries and company. To secure industries and companies this concept is helpful. RFID (Radio Frequency Identification) is one of the consistent and fast means of identify the material object. In the long ago the barcode’s are more preferable as compared to RFID because of their cost but now a day’s RFID are easily available and are more convenient to use. Research has made some drastic changes which makes its programming a lot shorter and easier is because of replacing microcontroller with Arduino. Arduino makes the circuit and programming a lot easier to understand. This project is based upon security access and control system using RFID and Arduino. Security access system is very convenient to use at home, office, hostels and commercial buildings.

Project Objectives

There has been rising demand for secure system that must be dependable and quick respond for the industries and company. To secure industries and companies this concept is helpful. RFID (Radio Frequency Identification) is one of the consistent and fast means of identify the material object. In the long ago the barcode’s are more preferable as compared to RFID because of their cost but now a day’s RFID are easily available and are more convenient to use. Research has made some drastic changes which makes its programming a lot shorter and easier is because of replacing microcontroller with Arduino. Arduino makes the circuit and programming a lot easier to understand. This project is based upon security access and control system using RFID and Arduino. Security access system is very convenient to use at home, office, hostels and commercial buildings.

The main objectives of this project are:

1. RFID based authentication system
2. Automatic opening of door when RFID tags matches

Project Implementation Method

Existing Method

 In the long ago the barcode’s are more preferable as compared to RFID because of their cost. In those days these barcode’s are available for low cost and they are popular in those days. The barcode is scanned by barcode reader and it displays the stored information, thus it provides security.

Limitations:

1. The Bar code should be placed nearer to the reader when compare to RFID tags.
2. These are very slow than the RFID readers.
3. These are inconsistent and inefficient.

Proposed Methodology

The proposed method is based on RFID (Radio Frequency Identification) technology. RFID tags are made to eventually replace barcodes in different chains. RFID tags or simply “tags” are small transponders that respond to queries from a reader by wirelessly transmitting a serial number or alike identifier. They are greatly used to track items in production environment and to label items in supermarkets. They are usually thought of as a highly developed barcode.

Technical Details of Final Deliverable

RFID system consists of three components namely transponder (tag), interrogator (reader) and computer containing the database as shown in Fig: No. 1 and Fig: No. 2 given below. The interrogator reads the tag data and transmits it to the computer for authentication. The information is processed and upon verification, access is granted. The system offers diverse frequency band ranging from low frequencies to microwave frequencies.

1. Low Frequency: 125-134 KHz
2. High Frequency: 13.56 MHz
3. Ultra High Frequency: 902-928 MHz
4. Microwave Frequency: 2.4 GHz

Depending upon the source of electrical energy, RFID tags are classified as either active or passive. The active tags use a battery for powering the circuit on the tag and transmit the tag information upon the reader request. However, these tags are very expensive and seldom used. On the other hands, passive tags get energy from the reader to power their circuit. These tags are very cost-effective and hence most of the applications use them.

In the present work, passive RFID tags have been used. A passive RFID tag transmits information to the reader when it comes near electromagnetic field generated by the reader. The phenomenon is based on Faraday’s law of electromagnetic induction. The current flowing through the coil of interrogator produces a magnetic field which links to the transponder coil thereby producing a current in the transponder coil. The transponder coil then varies this current by changing the load on its antenna. This variation is the modulated signal (scheme is known as load modulation) which is received by the interrogator coil through mutual induction between the coils. The interrogator coil decodes this signal and passes to the computer for further processing.
