Fingerprint-based access control system using Arduino and R307/Adafruit fingerprint sensor Part 3

Описание: Optical fingerprint scanners are prominent security devices nowadays. These scanners are low-cost and easy to use with any embedded hardware platform. The scanners have built-in memory and a controller to store and compare fingerprints. Usually, optical fingerprint scanners have a USB and/or UART port to communicate with external controllers or computers. The scanner handles enrollment and matching of fingerprints, which communicates results through a USB or UART interface. One of such optical scanners is an R307 fingerprint sensor. R307 is a member of the R30X family of optical fingerprint scanners from Hangzhou Grow Technology Co., Ltd. This fingerprint scanner is comparable to the Adafruit AS608 fingerprint sensor. The Adafruit fingerprint library works well with both AS608 and R30X sensors.

This project will design a fingerprint-based access control system using the R307 fingerprint sensor and Arduino. The fingerprint sensor is capable of storing and matching fingerprints. The results of the fingerprint scans can be further used for any access control like opening a door lock, logging into a computer, or starting a car/bike. This project demonstrates the development of a fingerprint access system. There are three stages for this – enrollment, fingerprint matching, and application-based deployment.
