| 31887 | UART Fingerprint Sensor (F) |
Features
This product uses a high-performance Cortex-core main controller and integrates a highly secure commercial fingerprint algorithm, supporting functions such as fingerprint enrollment, image capture, template extraction, and fingerprint comparison. There is no need to understand complex fingerprint recognition algorithms; you can carry out secondary development simply by sending commands over the serial port, making it suitable for integration into fingerprint recognition applications with high requirements for size and accuracy.
- Easy to use, with no need to understand the fingerprint algorithm or internal structure; the corresponding operations can be completed with simple commands
- Built-in commercial algorithm, supporting fingerprint enrollment, fingerprint comparison, fingerprint image extraction, and fingerprint template upload, with stable performance and fast recognition speed
- Capacitive fingerprint recognition with sensitive response; a finger only needs to lightly touch the capture window for fast recognition
- High hardware integration, with the main controller and fingerprint sensor integrated into one unit, making it easy to embed into small-size applications
- Built-in human body sensing device, with power-down sleep and touch wake-up functions for lower power consumption
- Capture window with LED, providing fingerprint capture indication
- Onboard UART serial and USB dual communication interfaces
- Can be connected to a PC for communication with the host software, or connected to embedded hardware platforms such as STM32 and Raspberry Pi
Application Scenarios
- Fingerprint locks
- Fingerprint safes
- Fingerprint access control
- Fingerprint time and attendance
