Waveshare 360° Fingerprint Recognition Sensor (Model D), Round fingerprint Sensor Biometric Security Systems for DIY Projects

Description:

Powered by a high-performance Cortex processor and integrated with an advanced commercial-grade fingerprint algorithm, the Waveshare Round All-in-One Capacitive Fingerprint Sensor (D) delivers fast and accurate biometric identification. This compact module supports essential functions like fingerprint enrollment, image acquisition, feature extraction, template generation and storage, and 360° fingerprint matching—all handled internally. With seamless UART communication, users can easily integrate the sensor into applications requiring high-precision biometric authentication, without needing to understand complex fingerprint algorithms. Its all-in-one design makes it ideal for space-constrained, security-sensitive embedded systems.

Features:

• Easy to use with some simple commands, you don't have to know any fingerprint technology or the module's inter structure.
• Commercial fingerprinting algorithm supports functions like fingerprint enrollment, fingerprint matching, fingerprint image acquisition, and fingerprint feature uploading, with 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-sized applications.
• Narrow stainless steel rim supports 360° Omnidirectional verification.
• Embedded human sensor, the processor will enter sleep automatically, and wake up when touched, lower power consumption.
• Onboard UART connector, easy to connect with hardware platforms like STM32 and Raspberry Pi.

 Pin Description:

• VIN: Power 3.3V
• GND: ground
• RX: Serial data input (TTL level)
• TX: Serial data output (TTL level)
• RST: Sleep Control Interface:
• High level: module power supply - start
• Low level: module power down - sleep
• WAKE: wake-up pin, when RST is at a low level (sleep), the fingerprint module will be activated by touching the surface of the collector with a finger, and this pin outputs a high level.
