In this project, we will connect the fingerprint sensor with Arduino for the biometric security system. As a fingerprint module we use the fingerprint scanner module R305. Security is a major concern in our daily lives, and digital barriers have become an important part of these security systems. The fingerprint sensor is one of the safest door locking systems because it allows you to identify and distinguish each person individually and accurately. In addition, the module is very small and can be stored anywhere. With portability and lower power consumption, you can take it anywhere.
This is a fingerprint sensor module with TTL-UART interface for direct connection to the microcontroller UART or PC via the MAX232 / USB-Serial adapter. The user can store the fingerprint data in the module and configure it in 1: 1 or 1: N mode to identify the person.
The fingerprint module can be connected directly to any microcontroller as well as to the Arduino board. This optical biometric fingerprint reader with outstanding features can be integrated into a variety of finished products, such. B. an access control system, a presence system, a safe and a car door lock system.
The fingerprint reader can perform a secondary development and be integrated into various end products.
Good image processing capabilities can successfully capture an image with a resolution of 500 dpi.
