The **Fingerprint Sensor R307S** is an optical biometric module designed for accurate fingerprint recognition and secure identity verification in embedded systems. It features an integrated fingerprint acquisition system with built-in DSP processing and FLASH memory, allowing it to perform fingerprint enrollment, storage, matching, and search functions directly on the module. The sensor communicates via a TTL UART serial interface, making it easy to connect with microcontrollers such as Arduino, ESP32, and other 3.3V/5V compatible systems. It supports both 1:1 verification and 1:N identification modes, making it suitable for access control, attendance systems, and security-based applications. With fast response time, stable performance, and compact design, the R307S is widely used in DIY electronics, educational projects, and professional biometric systems where reliable fingerprint authentication is required.
