So we decided to test a simple and cheap prototype to see if such a robust system could be developed using the tool of our choice arduino uno.
Rfid based door lock system using arduino.
But here a 12v rfid reader is used for an interfacing.
Arduino uno rfid based automatic door lock system using an arduino.
Considering this fact we developed a security system using rfid techniques which permits entry of authorized individual in the area where this system is installed.
As this is a rfid based system you must know what is rfid and how rfid works.
Rfid is defined as radio frequency identification.
What is rfid and how does it work.
6 to 12v power source i have used 3 x 18650 cells circuit diagram and explanation.
In this article you will learn how to make an arduino based rfid door lock system.
Rfid based security and access control system is more secure and fast responded as compared to the other system like biometric.
In countries like india such automatic systems are not cheap by any yardstick.
There are many rfid readers are available in the market with 5v 9v and 12v.
Rfid stands for radio frequency identification and it s a non contact technology that s broadly used in many areas such as personnel tracking access.
In this tutorial we are going to learn how the mfrc255 rfid reader works and how it can be interfaced with arduino in a number of projects like the arduino based rfid door lock system.
Interfacing of rfid with arduino can be done by the following steps.
By using arduino it is easy to access and works very quickly while burning the code it is like plug and play device.
The data in the rfid tags are read using.
That is why people opt out for rfid based security system.
The advantage of the rfid system is contact less and works without line of sight.
The digital data is encoded and saved into the rfid tags.
I hope you guys enjoy learning this project arduino codes and library.
Here we will make a smart rfid door lock by using arduino and ultrasonic sensor.
When we see sophisticated door management system s the price tag struck immediately along with the utility of course.
The circuit diagram of arduino and rfid based door.
The necessity of power supply for rfid readers varies from one product to another.
Circuit description of arduino and rfid based door access system.
