Waveshare Round UART Capacitive Fingerprint Sensor

Features B>
Based on high-performance cortex processor, combined with high-security commercial fingerprint algorithm, UART fingerprint sensor (D) has functions such as fingerprint enrollment, image acquisition, feature search, pattern generation and storage, fingerprint matching and so on. Without any knowledge of the accomplice fingerprint algorithm, all you need to do is just send some UART commands, quickly integrate it into fingerprint verification applications that require small size and high precision.

1. Easy to operate by some simple commands, no need to know any fingerprint technology or Inter structure
2. Commercial fingerprint algorithm, support functions such as fingerprint enrollment, fingerprint matching, fingerprint image acquisition and fingerprint charging function, stable performance, rapid identification
3. Sensitive capacitive detection, just touch the collection window lightly for quick verification
4. Highly integrated hardware, processor and sensor in a small chip, suitable for small size applications
5. Narrow stainless steel RIM, support 360 degree omnidirectional verification
6. Built-in human sensor, the processor will automatically enter sleep mode and wake up when you touch, lower power consumption
7. Onboard UART connector, easy to connect with hardware platforms such as STM32 and Raspberry PI1.
