Round All-in-one Capacitive Fingerprint Sensor (D)

Based on a high-performance Cortex processor, combined with a high-security commercial fingerprinting algorithm, the UART Fingerprint Sensor (D) features functionalities such as fingerprint enrolling, image acquisition, feature finding, template generating & storing, fingerprint matching and more!

Without any knowledge about the complicated fingerprinting algorithm, all you need to do is send some simple UART commands to quickly integrate it into fingerprint verification applications which require small size and high precision.

Features

• Easy to use by some simple commands
• Commercial fingerprinting algorithm, supports functions like fingerprint enrolling, fingerprint matching, fingerprint image acquisition, fingerprint feature uploading
• Capacitive sensitive detection, just touch the collecting window lightly for fast verification
• Highly integrated hardware, processor and sensor in one small chip, suitable for compact applications
• Narrow stainless steel rim, supports 360° omni-directional verification
• Embedded human sensor, the processor will enter sleep automatically and wake up when touched for lower power consumption
• Onboard UART connector, easy to connect with hardware platforms such as Raspberry Pi
