Rfid Based Door Lock System Using Arduino Uno

When we see sophisticated door management system s the price tag struck immediately along with the utility of course.

Rfid based door lock system using arduino uno. The connection with the arduino uno board is very simple. In this post you are going to learn about how to build an rfid and keypad based door lock using arduino. In countries like india such automatic systems are not cheap by any yardstick. This is a simple arduino project.

To open the door the user will have to first scan the right tag and then he will have to enter the correct password. 3 x led s red green blue 3 x 220 ohm resistors. In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matri. 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.

Since the display can also work at 3 3v we connect the vcc from both modules to the breadboards positive rail. At first let s connect the power of both the reader and the display. This rfid based access control system is built around arduino uno board rfid reader module solenoid lock and a few other components. Be careful the rfid reader must be connected to the 3 3v output of the arduino uno or it will be destroyed.

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 rfid tag consist of integrated circuit and an antenna integrated circuit is for the storage of the data and an antenna is for transmitting the data to the rfid reader module. Working of arduino based rfid door lock the rfid system consists of two components. Arduino uno rfid based automatic door lock system using an arduino.

An rfid tag and a reader. 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. But here a 12v rfid reader is used for an. Interfacing of rfid with arduino can be done by the following steps.

The components you are going to require for rfid based access control system using arduino are as follows. There are many rfid readers are available in the market with 5v 9v and 12v. 6 to 12v power source i have used 3 x 18650 cells circuit diagram and explanation. 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.
