The GT521F52 Optical Fingerprint Scanner Module with JST SH Connector is a high-performance fingerprint scanner. Which is useful for to access control, security, identification, and convenience. This optical sensor module is designed for easy integration into applications with serial interface (UART). We need two wires are for TX and RX and two wires for power supply (5V).
There are four types of fingerprint scanner: the optical scanner, the capacitance scanner, the ultrasonic scanner, and the thermal scanner. The GT521F52 Fingerprint Scanner Module is an optical scanner module. This optical scanner takes a visual image using a digital camera.
The idle module is woken by a finger touching the metal frame of the sensor. The pictures of the fingerprints are processed on-board by the fingerprint algorithm (low power 32-bit ARM Cortex-M3 processor) and convert it into strings of data. These so-called ‘templates’ are residing on the module configured as a USB mass storage device. They can store and share through a database with other modules in a network, allowing easy enrollment of many users.
