Arduino & Fingerprint Sensor Based Biometric Security System


In this project we will be Interfacing Fingerprint Sensor with Arduino for Biometric Security System. The type of fingerprint module we are using is R305 Fingerprint Scanner Module. Security is a major concern in our day to day life, and digital locks have become an important part of these security systems. Fingerprint sensor-based is one of the safest door locking system as it has the ability to identify and distinguish every person individually without making any error. Also, the module is very small that it can be kept anywhere and with the portability feature and less power consumption you can carry it to any place as well.
