It provides serial.
Rfid door lock block diagram.
Em 18 rfid reader operates at 125 khz and it comes with an on chip antenna and it can be powered with 5v power supply.
Fig 1 shows a user trying to open the door by placing an rfid tag near the rfid reader.
This system prevents a large destruction and loss the project is based on rfid rc522 module.
The tag near to rfid reader.

Nodemcu is an open source firmware and development kit that helps you to prototype or build iot.
Rfid stands for radio frequency identification.
Block diagram of the system node mcu.
The tag will often be small and portable with little to no electronics in it.
Rfid based door automatic management systemarduino rfid module rc522 simple project.
Arduino rfid door lock circuit diagram.
Rfid door lock can be made easily at your home and you can install it in any door.
The rfid door lock is a lock that is simple to install and allows the user to easily lock and unlock doors.
Secure your house by implementing this handy automatic door management system.
Rfid door locks and rfid attendance system are very popular now days and many hotels provide provide rfid tag to their customer to lock and unlock the door.
Don t know about rfid rc522 module i will explain later.
Arduino uno is the brain of this project.
This rfid based security system is based on micro controller at89c52 and comprises a rfid module a lcd module for displaying the status and a relay for opening the door.
These door lock is just.
Flow chart of the system.
Level 1 block diagram 10.
This circuit is mainly used for an interfacing of rfid reader with an arduino.
Glowing of caution led means that you are using the wrong tag.
It closes manually after five seconds.
This project can be enhanced by connecting an lcd display to display the outputs.
It will contain a rfid reader writer and a magnetic door lock for simple use.
If tag id matches with the id in the code lock will open for five seconds.
Any rfid system will consist of a rfid reader and a rfid tag.
The circuit of this project uses three separate parts namely a reader a controller and door lock.
Lcd is used to display messages.
The automatic door lock system circuit diagram using an arduino is shown below.
