How Does An Optical Fingerprint Scanner Work?.

Therefore, it is easy to adapt the library that you find here for other models as well. Despite using different sensing techniques and form-factors, they all share the same interface and command set. R307 is an optical fingerprint scanner module from the R30X series produced by a Chinese vendor called Hangzhou Grow Technology Co., Ltd. In this tutorial, we will learn how an Optical Fingerprint Scanner works and how we can interface the R307 fingerprint scanner module to an Arduino board. There exist many methods to digitize fingerprints from forensic methods to ultrasound scanning. Before we can process a fingerprint pattern with a computer, we must “capture” it.

But computers are good at recognizing and matching patterns very fast and accurately. But just by holding someone’s hand and staring at their fingers can’t be practical 😁 we’re not good at it. So I have taken advantage of this feature of pro micro to get input from fingerprint and match the fingerprint With already loaded fingerprints to perform different keyboard operation.Fingerprints are one of the many unique biometric signatures we can use to identify people very accurately. The Micro is a microcontroller board based on the ATmega32U4,This allows the Micro to appear to a connected computer as a mouse and keyboard, Here I have used Arduino Uno for enrolling the fingerprint through SFGDemo Software.

Average searching time: < 0.8s (1:880).

Interface : UART (TTL logical level)/ USB 1.1.The finger print module can directly interface with 3v3 or 5v Microcontroller.įeatures of Finger Print Sensor (R305) -TTL UART:

The user can store the finger print data in the module and can configure it in 1:1 or 1: N mode for identifying the person.

Finger Print Sensor (R305) -TTL UART is a finger print sensor module with TTL UART interface.
