Fingerprint Scanner 指紋採集 TTL 模組 可儲存 200 組 高精度指紋識別 SparkFun原廠
NTD $3010
Fingerprint Scanner 指紋採集 TTL 模組 通過TTL Serial進行通信，
因此您可以輕鬆將其嵌入到您開發的項目中，模組本身完成了SmackFinger 3.0算法的高速，高精度指紋識別 識別的指紋與板載光學傳感器和32位CPU。所有你需要做的是發送簡單的命令。
要開始，只需通過發送相應的命令並將您的手指按壓三次，就可以註冊要存儲的每個指紋。
指紋掃描器可以存儲不同的指紋，甚至可以從單元下載打印數據庫並分發給其他模塊。
除了指紋“模板”，打印的分析版本，還可以檢索指紋的圖像，甚至從光學傳感器中拉出原始圖像！
商品說明
Fingerprint Scanner 指紋採集 TTL 模組 可儲存 200 組 高精度指紋識別
模組能存儲多達200種不同的指紋，但可以使用串行接口360°指紋識別和下載和上傳模板。如果你是一個預算，只需要少量的指紋存儲，這是你的完美選擇！該模塊體積小巧，易於安裝，使用傳感器側面的兩個安裝卡舌。板載JST-SH連接器有四個信號：Vcc，GND，Tx，Rx。以下相關項目可以找到兼容的JST-SH尾纖。PC的演示軟件可以在以下文檔中使用，只需使用FTDI Breakout將模塊連接到計算機，並啟動軟件讀取指紋！

Fingerprint Scanner – TTL (GT-521F32)
Fingerprint Scanner – TTL High-Speed, High-Accuracy Fingerprint Identification using the SmackFinger 3.0 Algorithm
Fingerprint scanners are awesome! Why use a key when you have one right at the tip of your finger? Unfortunately, they’re often unreliable or difficult to implement. Well not anymore! This great GT-521F32 fingerprint module from ADH-Tech communicates over TTL Serial so you can easily embed it into your next project. The module itself does all of the heavy lifting behind reading and identifying the fingerprints with an onboard optical sensor and 32-bit ARM Cortex M3 processor.
To get started, just register each fingerprint that you want to store by sending the corresponding command and pressing your finger against the reader three times. The fingerprint scanner can store different fingerprints, and the database of prints can even be downloaded from the unit and distributed to other modules. In addition to the fingerprint “template,” the analyzed version of the print, you can retrieve the image of a fingerprint and even pull raw images from the optical sensor!
This module is the economical version of the GT-521F52 and can store up to 200 different fingerprints. It is capable of 360° fingerprint recognition and download/upload templates using serial interface. Additionally, the GT-521Fxx series features a resolution of 450dpi, with a false acceptance rate of <0.001% and a false rejection rate of <0.1% while only needing <1.5 seconds to identify a unique fingerprint!
Note: Please be aware that even though this fingerprint scanner is equipped with the same connector we use on all of our Qwiic boards, it is NOT Qwiic or I2C compatible. That being said, all of our Qwiic cables, like our 100mm version, will work for this board.
