Rfid Based Door Access Control Using Arduino

In this post you are going to learn about how to build an rfid based access control system using arduino.

Rfid based door access control using arduino.

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. The system combines rfid technology and arduino to accomplish the required task. 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. To enter passwords and to allow access to a door or to drive an electronic device now we will use a rfid device.

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. The system i have designed here is a simple version of the project. 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. We was also be able to open the door lock and halt the system by sending the message to arduino.

Interfacing is the first step to create any useful project. 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. 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. Security system and access control with arduino and rfid project tutorial by sarath p.

The advantage of the rfid system is contact less and works without line of sight. In the previous article we saw how to interface rfid with arduino. In this paper automatic rfid based access control system using arduino was designed. Its quiet fun to work with rfid based projects.

Rfid based security and access control system is more secure and fast responded as compared to the other system like biometric. So why don t we create an rfid based access control system or an rfid based door lock using arduino. This rfid based access control system is built around arduino uno board rfid reader module solenoid lock and a few other components.
