Fingerprint Door Lock Project Circuit Diagram

Fingerprint sensor is the main part of this system.

Fingerprint door lock project circuit diagram.

Servo motor is responsible for open and closing of the gate. Circuit diagram of the fingerprint door unlock system. It can store up to 750 finger prints on its own memory. I m working on a project that requires me to design a system that measures the approximate length of the five fingers of a person and i have very little idea of how to go about it.

As thefts are increasing day by day security is becoming a major concern nowadays. I ll be really grateful for your help. It is also called as biometric sensor. Armature surrounded by a big coil of copper wire forms a solenoid.

Can you help with more ideas circuit diagrams block diagrams most esspecially. You can add a fingerprint delete a fingerprint and identify the fingerprint. The micro controller at89s52 interacts with the module. 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.

An arduino microcontroller mcu requires only 5v but the solenoid electric lock requires 12v. Arduino fingerprint door lock with keypad and lcd. As arduino uno has an inbuilt 5v voltage regulator a common 12v supply can be used for the whole system. It makes use of biometric sensor to detect fingerprint.

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 circuit of this arduino fingerprint security system is very simple which contains arduino which controls whole the process of the project push button buzzer and lcd. It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. It will open your door only when the right password is entered.

In this project we will learn how to make password based door lock security system using arduino keypad. Electronic door lock solenoid arduino fingerprint sensor lock. Fingerprint door lock circuit diagram. It is nothing new but almost similar to an electromagnet.

For controlling the door lock you will need a battery source from 7 to 12v i used three 18650 cells. 1 operates using a 12v power supply. The user may customize gate door opening and closing according to their requirement. It is connected to the output of relay as show in circuit diagram.

Fingerprint sensor uses various types of techniques like ultrasonic method optical method or thermal technique. In this project the fingerprint module from mixes biometrics is used. The circuit shown in fig. A slug of metal i e.

So a digital code lock can secure your home or locker easily. Download the project libraries. It can be controlled through its serial port.
