Sensor sidik jari Optical Fingerprint Reader Sensor Module for Arduino

Make adding fingerprint detection and verification super simple. Typically used in safes there is a high powered DSP chip that does the image rendering, calculation, feature finding and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash and search. You can also enroll new fingers directly up to 240 finger prints can be stored in the onboard FLASH memory. There is a Red LED in the lens that lights up during a photo so you know it is working.

Item Description:
Supply voltage : DC 3.8 to 7.0V
Supply Current : Current : less than 60mA

Fingerprint image time : less than 0.5 s Window
Size : 15 x 17 mm
Signature File : 384 bytes
Template files : 786 bytes
Storage capacity: 240
False Accept Rate: less than percent 0.001 security level 3 False Reject Rate : less thanpercent 1.0 security level 3 Search time: less than 220 ms 1:240 , the mean PC Interface : UART TTL logic level C

Hardware connection:
Module via serial communication interface, directly with 3.3V or 5V power microcontroller communication: module data transmission feet( foot TD) connected to the data bit machine receiving end(RDX), data receiver module (3 feet RD) connected to the data sender bit machine (TXD).
For the RS-232 level( for example: PC machine) for pc communication, increase the level conversion between the module and the host computer Circuitry(e.g.: max232 circuit)
