Fingerprint Door Lock Project Circuit Diagram

So a digital code lock can secure your home or locker easily.

Fingerprint door lock project circuit diagram.

An arduino microcontroller mcu requires only 5v but the solenoid electric lock requires 12v. In this project the fingerprint module from mixes biometrics is used. Pls i might need a little help from you. It can be controlled through its serial port.

The user may customize gate door opening and closing according to their requirement. 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. 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.

I ll be really grateful for your help. A slug of metal i e. It can store up to 750 finger prints on its own memory. It makes use of biometric sensor to detect fingerprint.

It is nothing new but almost similar to an electromagnet. In this project we will learn how to make password based door lock security system using arduino keypad. The circuit shown in fig. Circuit diagram of the fingerprint door unlock system.

1 operates using a 12v power supply. It uses a keypad and fingerprint scanner to grant a user access by controlling an electric door s. It is also called as biometric sensor. Fingerprint sensor uses various types of techniques like ultrasonic method optical method or thermal technique.

For controlling the door lock you will need a battery source from 7 to 12v i used three 18650 cells. Armature surrounded by a big coil of copper wire forms a solenoid. As arduino uno has an inbuilt 5v voltage regulator a common 12v supply can be used for the whole system.
