We ll start with explaining the underlying tech before walking through a tutorial of how you armed with little more than an arduino and some rfid tags and a sensor can implement your own door.
Rfid door lock block diagram.
Block diagram of door security system using rfid rc522.
How rfid works and how to make an arduino based rfid door lock howtomechatronics retrieved 15 october.
Servo motor is used to indicate that the door is opening or closing.
The rfid reader is placed on the outside of the door and it is detached from the controller confidentially so no one can avoid the security by breaking open the rfid reader and trying to short circuit the reader.
Figure 5 shows the access control system block diagram using arduino and rfid.
The rfid door lock is a lock that is simple to install and allows the user to easily lock and unlock doors.
It provides serial.
The tag will often be small and portable with little to no electronics in it.
Arduino rfid door lock circuit diagram.
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.
This project guide will detail the steps to create an rfid radio frequency identification door lock system using an arduino mega 2560.
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.
Any rfid system will consist of a rfid reader and a rfid tag.
The controller of this project receives serial information from the rfid reader and.
Level 1 block diagram 10.
This system prevents a large destruction and loss the project is based on rfid rc522 module.
Automatic door lock system circuit diagram.
It will contain a rfid reader writer and a magnetic door lock for simple use.
If the wrong tag is scanned the door will stay closed and set off a buzzer.
Lcd is used to display messages.
Level 0 block diagram 7 2.
Rfid stands for radio frequency identification.
Each rfid card has a unique id embedded in it and a rfid reader is used to read the rfid card no.
