R307 Fingerprint Sensor Module UART Optical Biometric Reader for Arduino
VAT inclusive; Computed calculations added locally.
Overview
The R307 Fingerprint Module is a compact optical biometric sensor designed to make fingerprint detection and identification easy to integrate into embedded electronics projects. With its built-in processing system and TTL UART serial interface, the module can communicate directly with compatible microcontrollers without requiring additional fingerprint-processing hardware.
The sensor captures a fingerprint image, extracts the relevant fingerprint features, and compares them against fingerprints stored in its internal memory. It supports both 1:1 verification and 1:N identification, allowing developers to build systems that either verify a specific enrolled user or search the stored database for a matching fingerprint.
The R307 is widely used in Arduino-based biometric projects, attendance systems, electronic safes, access-control prototypes, smart locks, and home automation applications. Its UART interface makes communication straightforward, while its integrated processing reduces the workload placed on the host microcontroller.
