Fingerprint Sensor Door Lock Arduino

You can add a solenoid instead of this led and make a fingerprint door lock which could be a brief tutorial for the future but for this tutorial led indication is our eureka.

Fingerprint sensor door lock arduino.

Conclusion in this tutorial post we learned how to set up a fingerprint sensor and how to use it with our arduino you can use this knowledge to control a. A fingerprint lock would be help for me and there are plenty of these kinds of locks on the market as the picture above. The whole system is run with dual arduino unos and powered by portable battery packs. But it is not only expensive and it is also very troublesome to install.

A fingerprint lock would be help for me and there are plenty of these kinds of locks on the market as the picture above. Not only to ensure door security this project also make certain to assist in fields like forensics crime investigation personal identification attendance system and there is a lot more. In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. These modules can be added to security systems door locks time attendance systems and much more.

First of all connect the fingerprint sensor to the arduino uno. The easiest way to control the fingerprint sensor module with the arduino is by using the adafruit library for this sensor. The default pins for serial communication on the arduino uno are pin 0 rxd and pin 1 txd of the board but we are going to use other pins for serial communication. Make sure you get a fingerprint sensor that works with the arduino through the serial communication.

Finger print is considered one of the safest key to lock or unlock any system as it can recognize any person uniquely and can t be copied easily. After learning arduino for 2 weeks i decided to diy a fingerprint lock with arduino. Prices for this sensor greatly vary from 10 to 50. Follow the next instructions to install the library.

But it is not only expensive and it is also very troublesome to install. From outside the door a person is greeted with a fingerprint sensor and a display saying if the door is locked or unlocked. You need adafruit finge. Having them run off battery enables the system to keep running even during a black out.

I hope to find a cheap way and do need not change my locks. How to make fingerprint door lock at home from this tutorial you can make awesome fingerprint sensored locking system for your door.
