Password based door lock system using 8051 microcontroller is a simple project where a secure password will not enough to act as a door unlocking system since any body can use the password and open the door.
Rfid door lock system circuit.
Program a code and upload it to arduino just like a plug and play device.
These are systems where the tag has its own power source like any external power supply unit or a battery.
An rfid based door lock is based on some simple concepts.
In this post you are going to learn about how to build an rfid based access control system using arduino.
Arduino rfid door lock circuit diagram.
When the person with the right rfid card compatible to data preloaded in our program system come and swipes his rfid tag access will be granted.

It can be a host computer with a microprocessor or a microcontroller which receives the reader input and process the data.
With the use of arduino it becomes much easy to design.

We store a set of rfid card data in our system say 3 or 10 rfid card data.
Automatic door lock system circuit diagram.
Rfid stands for radio frequency identification.
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.
Each rfid card has a unique id embedded in it and a rfid reader is used to read the rfid card no.
The arduino based rfid door lock system is secure and responsive as compared to other systems.
The controller of this project receives serial information from the rfid reader and.
2 types of rfid systems.
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.
It provides serial.
To overcome this we design rfid password and otp based door lock system using 8051 microcontroller.
It is simple and cost efficient project and can be used as a basic access control mechanism.
The only constraint being the life time of the power devices.
In the previous post you learned about rfid and keypad based door lock and alert system using arduino in which user had to scan the right tag and enter the right password to open the door lock and the system also sends us the confirmation message.
