Round-Shaped All-In-One Capacitive Fingerprint Reader (D) – Cortex Processor, 360° Verification
The UART Fingerprint Sensor (D) is a module with 360° capacitive verification, operated via UART commands. Based on a high-performance Cortex processor, combined with a commercial high-security fingerprint algorithm, the sensor offers functions such as fingerprint enrolling, image acquisition, feature finding, template generation and storage, fingerprint matching, etc.
Without any knowledge of complex fingerprint algorithms, you just need to send a few UART commands to quickly integrate it into fingerprint verification applications that require small size and high precision.
Key Features:
- Easy to use with simple commands, no knowledge of fingerprint technology or internal module structure required
- Supports functions such as fingerprint enrolling, fingerprint matching, fingerprint image acquisition, and fingerprint feature uploading
- Capacitive touch detection, just lightly touch the collecting window for fast verification
- Highly integrated hardware, processor, and sensor in one small chip
- Narrow stainless steel rim, supports 360° omni-directional verification
- Built-in touch sensor, the processor automatically enters sleep mode and wakes up on touch, ensuring lower power consumption
- Onboard UART connector, easy to connect with hardware platforms like STM32 and Raspberry Pi
