An rfid based door lock is based on some simple concepts.
Rfid based automatic door locking system project.
First the user combination will be compared with prerecorded password which are stored in the system memory.
Coolest door lock ever project tutorial by vivek gupta.
This rfid door lock can be made easily at your home and you can install it in any door.
The automatic door lock system circuit diagram using an arduino is shown below.
User can go for certain number of wrong combinations before the system will be temporarily disabled.
It s very important to authenticate the user before entering into a secure space and rfid provide this solution.
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.
Just thought of making a password based door lock system in which you can enter the password via the keypad.
It also keeps the record of check in and check out of the user.
This project can be enhanced by connecting an lcd display to display the outputs.
The cyclops eyes will turn red on wrong rfid tag and green on authorized rfid tag.
You have seen rfid door lock mechanism in some hotels and other places where you don t need a key to unlock the room.
Arduino rfid door lock hardware project setup.
A digital door locking system is also implemented and governed by rfid reader which authenticate and validate the user and open the door automatically.
This allows the user to lock unlock his home s door lock by using a smartphone from anywhere in the world.
In countries like india such automatic systems are not cheap by any yardstick.
When we see sophisticated door management system s the price tag struck immediately along with the utility of course.
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.
You are given a card and you just need to put it in front of a rfid reader box and the lock gets unlocked with a beep and a blink of led.
We store a set of rfid card data in our system say 3 or 10 rfid card data.
Here nodemcu will act as the main controller and connect the user to the door lock system using the internet.
This circuit is mainly used for an interfacing of rfid reader with an arduino.
This automatic password based lock system will give user more secure way of locking unlocking system.
So in this project we are going to make an iot based door lock system using nodemcu solenoid lock and adafruit io.
It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
