This is the R307 Fingerprint Sensor Module with a TTL Uart Interface for direct connection to microcontroller uart or to PC through MAX 232/USB-serial adapter. The user can save the fingerprint data in the Module and can configure it in either 1:1 or 1 :N mode for identification of the person. The Fp module can directly interface with three.3 or five volt microcontroller. An integrated image collecting and algorithm chip, All-in-One Fingerprint Reader can conduct secondary development, be embedded into a variety end products. Users can perform secondary development, can be used in a variety of end products including access control, attendance, safety deposit box, car door lock. The R307 Fingerprint sensor module has low power consumption, low-cost, small size, excellent performance, professional optical technology, precise module manufacturing technics. Good image processing capabilities can successfully collect an image up to resolution500dpi Finger detection function
