Optical UART Serial Fingerprint Recognition Sensor Module for Arduino
This is 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£¬ door. There's 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 finger prints can be stored in the onboard FLASH memory. There's a blue LED in the lens that blinks after taking a photo so you know its working. Features: - Can be directly connected to Arduino UNO R3 - The 6P cable help you to connect the sensor to 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 DIY
