Fingerprint based security system is the most secured system as compared to other systems. The device is the most popular among all the identification devices because of its ease in acquisition and also the number of sources that are available for its data collection. 1 operates using a 12v power supply. Fingerprint door lock circuit diagram.

It is connected to the output of relay as show in circuit diagram. Finger print is considered one of the safest key to lock. Download the project libraries. Introductionthe fingerprint door lock as the name suggests is an electronic door lock that can be installed on almost any access point in your house.

The libraries for fingerprint sensor and i2c lcd are easily available. History of fingerprint scanners this identification device has been commercialized from the late 19 th century. Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock. The circuit shown in fig.

In this post we will interface a fingerprint sensor module with arduino and will build a fingerprint based biometric security system with door locking. For controlling the door lock you will need a battery source from 7 to 12v i used three 18650 cells. Want to carry out a project like this but wish to combine password and fingerprint together. It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s.

If you want to buy the entire combo for the project then click here enrollment code code 1 include adafruit fingerprint h include softwareserial h. The fingerprint module can be directly interfaced with any microcontroller as well as arduino board. However thumbnail of every human being is unique so lock will not open unless the same person is present to give the impression of fingerprint. A slug of metal i e.

Code and circuit diagram for fingerprint sensing door locking system july 3 2019 january 22 2020 admin 0 comments. To add a fingerprint just show the finger on the module and press the add key. Can you pls help with the circuit diagram and the list of components. Arduino fingerprint door lock with keypad and lcd.

Circuit diagram of the fingerprint door unlock system. Electronic door lock solenoid arduino fingerprint sensor lock. As arduino uno has an inbuilt 5v voltage regulator a common 12v supply can be used for the whole system. An arduino microcontroller mcu requires only 5v but the solenoid electric lock requires 12v.

I enjoy reading your blog fingerprint based security system and door lock.
