This capacitive fingerprint sensor supports fingerprint capture, processing, fingerprint storage, fingerprint comparison, and so on.Taking ID809 high-performance processor and semiconductor fingerprint sensor as the core, the sensor adopts built-in IDfinger6.0 algorithm, which can complete all fingerprint identification work independently.The product supports UART communication. When working with the library, it can realize functions like fingerprint registration, fingerprint deletion, etc. Also, we upper computer software that helps users to operate this sensor.This fingerprint sensor comes with round breathing and has a simple structure, small size, and delicate appearance. The sensor offers fast recognition speed and high security.Whats more, it supports 360-degree arbitrary angle recognition and deep self-learning function, high performance and low power consumption.CNC metal ring, plus ,Applications,Fingerprint door-lock,Drawer Lock,Identity Recognition,AuthorizationOperating Voltage: 3.3VOperating Current: less than 60mACommunication : UARTStorage Capacity: 80 1:1 verification time: 300~400msPixel Resolution: 508dpiNumber of Pixels: 160x160Fingerprint Detection Area: 8.0mm x 8.0mmWorking Environment: 4060/ less than RH 90%Dimension: diameter 21mm/height 5mmcolour: blackMaterial: metalPackage Contents:1 x capacitive fingerprint scanner/sensor 1 x PH1.0 6P cableOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
