Rfid Based Door Access Control Using Arduino

We was also be able to open the door lock and halt the system by sending the message to arduino.

Rfid based door access control using arduino.

The system combines rfid technology and arduino to accomplish the required task. Its quiet fun to work with rfid based projects. In this post you are going to learn about how to build an rfid based access control system using arduino. Security system and access control with arduino and rfid project tutorial by sarath p.

Rfid is a non contact automatic identification technology that uses radio signals to identify track sort and detect a variety of objects including people vehicles goods and assets without the need for direct contact or line of sight contact as found. In the previous post you learned about rfid and keypad based door lock and alert system using arduino in which user had to scan the right tag and enter the right password to open the door lock and the system also sends us the confirmation message. To enter passwords and to allow access to a door or to drive an electronic device now we will use a rfid device. So why don t we create an rfid based access control system or an rfid based door lock using arduino.

Interfacing is the first step to create any useful project. The advantage of the rfid system is contact less and works without line of sight. Rfid based security and access control system is more secure and fast responded as compared to the other system like biometric. In the previous post we made an rfid based access control and alert system using arduino in which system sends us messages when the access was granted or denied.

In the previous article we saw how to interface rfid with arduino. We also will use a lcd display with 20 character and 4 lines to show some messages from the system besides a servo motor to drive an mechanical device like door s. This rfid based access control system is built around arduino uno board rfid reader module solenoid lock and a few other components. By using arduino it is easy to access and works very quickly while burning the code it is like plug and play device.

In this paper automatic rfid based access control system using arduino was designed. The project arduino and rfid based door access system is basically an access control system and can be placed where authorize entry is compulsion like office school etc. Instead of using a matricial keyboard to enter passwords and to allow access to a door or to drive an electronic device now we will use a rfid radio frequency identifier device.
