Optical Fingerprint Sensor (UART, 1000 Fingerprints)
Introduction
This is an Arduino compatible fingerprint module. With the high speed DSP processor, it could also work with other serial device, like MSP430, 51, AVR, PIC, STM32, ARM and FPGA device. This fingerprint module could work alone without any principal computer or any PC software. It could store 1000 fingerprints. Support fingerprint entry, intelligent image processing, fingerprint comparison and fingerprint search mode. It also has a high sensitivity to both wet and dry fingerprint recognition.
This module could be widely used in security field, such as license management .etc. It can also be used to replace the IC card, password, hardware switch in your application.

Reliable and easy-to-use optical fingerprint sensor! I tested it with an ESP32 and it performed flawlessly. The UART interface is simple to integrate, and enrolling or verifying fingerprints is very fast. It can store up to 1000 templates, making it perfect for access-control or attendance systems. The sensor’s recognition accuracy is excellent, even with slightly wet or dusty fingers. Build quality is solid, and the examples provided by DFRobot make setup quick and straightforward. Highly recommended for any IoT or embedded security project.
