Secure your house by implementing this handy automatic door management system.
Rfid door lock block diagram.
Flow chart of the system.
Fig 1 shows a user trying to open the door by placing an rfid tag near the rfid reader.
It provides serial.
The automatic door lock system circuit diagram using an arduino is shown below.
Each rfid card has a unique id embedded in it and a rfid reader is used to read the rfid card no.
Servo motor is used to indicate that the door is opening or closing.
These door lock is just.
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.
Nodemcu is an open source firmware and development kit that helps you to prototype or build iot.
The circuit of this project uses three separate parts namely a reader a controller and door lock.
It will contain a rfid reader writer and a magnetic door lock for simple use.
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.
Arduino uno is the brain of this project.
Level 1 block diagram 10.
The tag will often be small and portable with little to no electronics in it.

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.
Rfid and keypad door lock and alert system using arduino.
Glowing of caution led means that you are using the wrong tag.
The rfid door lock is a lock that is simple to install and allows the user to easily lock and unlock doors.
Glowing of led indicate that the lock is open.
The tag near to rfid reader.
This circuit is mainly used for an interfacing of rfid reader with an arduino.
Any rfid system will consist of a rfid reader and a rfid tag.

This system prevents a large destruction and loss the project is based on rfid rc522 module.
Rfid stands for radio frequency identification.
Don t know about rfid rc522 module i will explain later.
Rfid door lock can be made easily at your home and you can install it in any door.
