Optical UART Serial Fingerprint Recognition Reader Sensor Module TTL Control Up to 500 Finger Prints

Description This is a fingerprint recognition sensor with UART TTL serial port and it is easy to use because it uses only 8 AT commands It can be used to secure your project with biometrics this all in one optical fingerprint sensor will make adding fingerprint detection and verification super simple These modules are typically used in safes such as drawers doors Theres 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 500 fingerprints can be stored in the onboard FLASH memory Theres a blue LED in the lens that blinks after taking a photo so you know its working Features Can be directly connected to UNO R3 The 6P cable helps you to connect the sensor to the Arduino or other MCU development board Working voltage 4 4 6 0VDC Working current 120mA max Peak current 140mA max Fingerprint imaging time 1 0 seconds Signature file 256 bytes Template file 512 bytes Storage capacity 500 templates Safety level 3 False Acceptance Rate 0 001 Security level 3 False Reject Rate 1 0 Security level 3 Interface UART TTL Serial Baud rate 57600 Communication format 8N1 Great for DIYPackage includes 1 x Fingerprint recognition sensor with cable
