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 registration, matching and image capturing, and is suitable for small applications with high precision thanks to simple UART commands.
Features:
- Simple operation through simple commands.
- Commercial fingerprint algorithm with stable performance and fast identification.
- Capacitive detection for quick validation through light touch. Built-in 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.
Example Applications for Fingerprint Reader:
- Fingerprint lock
- Safe box with fingerprint
- Access control system with fingerprint scanner
- Door lock system with fingerprint
- Time attendance system
