UART Fingerprint Sensor (G)

High-precision | UART communication | LED indicator | All-In-One

Product Features:

Based on a high-performance Cortex processor, combined with high-security commercial fingerprinting algorithm, the UART Fingerprint Sensor (G) features functionalities like fingerprint enrolling, image acquisition, feature finding, fingerprint matching, and so on. Without any knowledge about the complicated fingerprinting algorithm, all you need to do is just send some UART commands, to quickly integrate it into fingerprint verification applications which require small size and high precision.

• Easy to use by some simple commands, you don't have to know any fingerprint technology, or the module internal structure
• Commercial fingerprinting algorithm, supports functions like fingerprint enrolling, fingerprint matching, fingerprint image acquisition, and fingerprint feature uploading, stable performance, fast identification
• Capacitive sensitive detection, just touch the collecting window lightly for fast verification
• Highly integrated hardware, processor and sensor in one small chip, suitable for small size applications
• Embedded human sensor, the processor will enter sleep automatically, and wake up when touching, lower power consumption
• Onboard collecting window indicator for fingerprint capture indication
• Onboard UART communication interface
• Supports connection to a PC for communication with upper computer software, and is also compatible with embedded hardware platforms like STM32 and Raspberry Pi
