Microcontroller Based Code Access Control System (Password Protected)

SYNOPSIS

Now a days, a problem of security is very much important everywhere in the world. So, in large firms or companies, to make protect of entering of unauthorized person or to secure their important section, they generally use this type of security.

This project, AN ACCESS CONTROL SYSTEM provides a facility of security. This type of security lock is generally attached at the main entrance door of the firms. By using this type of security, only authorized fellow can enter.

It is quite easy in installation and use. Through this, one can allocate more number of passwords to many fellows. It is easy to use as the fellow don’t need to carry any type of id card or chip etc.

CIRCUIT DIAGRAM

DESRIPTION

When the power supply is switched on, then the whole circuit starts working.

Then in LCD, the name of company is displayed and the person is asked to enter the password.

The password is entered through a hex keypad.

The microcontroller compares that password with the already saved database of employee's information.

If it matches with any of the saved password, then microcontroller gives output to the LCD.

Then in LCD, the name of employee, his department, his employee number, etc are displayed.

Parallel, the microcontroller gives output to the DC motor to open the door.

If the password doesn’t match with any password three times, then microcontroller displays in LCD that your password is wrong, and it gives output to the buzzer.

BLOCK DIAGRAM & DESCRIPTION

First of all a user enters a password by a hex keypad.

Micro controller checks password and then gives according output.

If the password is correct then it opens the door.

If the password is wrong then it gives output to the alarm.

RFiD Based Door Access Control

RFiD Based Door Access Control

SYNOPSIS

The concept of access control is brought about using a card, a corresponding card reader and a control panel interfaced with the server. The card is a proximity card with a unique identification number integrated in it. The reader reads the data and sends it to the control panel, which is the micro controller. This controller checks the validity of the data with the server, which bears the database. The server is loaded with the details about the employee for that number.

The control panel checks whether he/she is allowed to enter the particular door or not. If the employee is authentic, then he/she is allowed access in the particular entrance.

The employees can be permitted in a given entrance as per his/her designation. The access control is employed at this point. When a person of a particular designation is not supposed to be allowed in a given entrance.

RFID

Radio frequency (RF) refers to electromagnetic waves that have a wavelength suited for use in radio communication. Radio waves are classified by their frequencies, which are expressed in kilohertz, megahertz, or gigahertz. Radio frequencies range from very low frequency (VLF), which has a range of 10 to 30 kHz, to extremely high frequency (EHF), which has a range of 30 to 300 GHz.

RFID is a flexible technology that is convenient, easy to use, and well suited for automatic operation. It combines advantages not available with other identification technologies. RFID can be supplied as read-only or read / write, does not require contact or line-of-sight to operate, can function under a variety of environmental conditions, and provides a high level of data integrity. In addition, because the technology is difficult to counterfeit, RFID provides a high level of security.

RFID is similar in concept to bar coding. Bar code systems use a reader and coded labels that are attached to an item, whereas RFID uses a reader and special RFID devices that are attached to an item. Bar code uses optical signals to transfer information from the label to the reader; RFID uses RF signals to transfer information from the RFID device to the reader.

Radio waves transfer data between an item to which an RFID device is attached and an RFID reader. The device can contain data about the item, such as what the item is, what time the device travelled through a certain zone, perhaps even a parameter such as temperature. RFID devices, such as a tag or label, can be attached to virtually anything – from a vehicle to a pallet of merchandise.

RFID technology uses frequencies within the range of 50 kHz to 2.5 GHz. An RFID system typically includes the following components:

• An RFID device (transponder or tag) that contains data about an item

• An antenna used to transmit the RF signals between the reader and the RFID device

• An RF transceiver that generates the RF signals

• A reader that receives RF transmissions from an RFID device and passes the data to a host system for processing
