WaveShare Capacitive 360-degree fingerprint sensor (D) with UART

The UART fingerprint sensor is equipped with a powerful Cortex processor and a highly secure fingerprint algorithm. It enables functions such as enrollment, matching, and image capture, making it suitable for small applications that require high precision, thanks to the simple UART commands.

Features:

• Easy operation through simple commands.
• Commercial fingerprint algorithm with stable performance and fast identification.
• Capacitive detection for fast verification by light touch. Integrated hardware for small applications.
• Stainless steel rim for 360° omnidirectional verification.
• Embedded sensor with low power consumption.
• Integrated UART port for easy connection to hardware platforms.

Application examples for the fingerprint reader:

• Fingerprint lock
• Safe deposit box with fingerprint
• Access control system with fingerprint scanner
• Door locking system with fingerprint
• Coming and going time recording
