描述
Fingerprint Scanner – TTL (GT-511C3) 指紋掃描模組 美國 SparkFun 原裝進口
模組本身完成所有的指紋掃描繁重工作，其中包括在車載光學傳感器和32位CPU上讀取和識別指紋。所有你需要做的就是發送簡單的命令。要開始使用，只需通過發送相應的命令並將手指按在閱讀器上三次，即可註冊要存儲的每個指紋。指紋掃描儀可以存儲不同的指紋，打印數據庫甚至可以從本機下載並分發到其他模組。除了分析版本的指紋“模板”外，您還可以檢索指紋圖像，甚至從光學傳感器中提取原始圖像！
這是具有增加的內存容量的GT-511的更新版本。該模組可以存儲多達200個不同的指紋（這是舊版本的10倍！），現在可以360°識別。
該模組體積小，易於使用傳感器側面的兩個安裝片進行安裝。板載JST-SH連接器有四個信號：Vcc，GND，Tx，Rx。兼容的JST-SH尾纖可以在下面的相關項目中找到。下面的文檔提供了用於PC的演示軟件，只需使用FTDI Breakout將模組連接到計算機，然後啟動軟件讀取指紋！
感測器特色：
- 使用SmackFinger 3.0算法實現高速，高精度的指紋識別
- 從設備下載指紋圖像
- 讀寫指紋模板和數據庫
- 簡單的UART協議（默認9600波特）
- 能夠進行1：1驗證和1：N驗證
- 37 x 17 x 9.5毫米

Fingerprint Scanner – TTL (GT-511C3)
Fingerprint scanners are awesome. Why use a key when you have one right at the tip of your finger? Unfortunately, they’re usually unreliable or difficult to implement. Well not anymore! We’ve found this great fingerprint module from ADH-Tech that 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 on-board optical sensor and 32-bit CPU. All you need to do is send it simple commands. 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. As well as the fingerprint “template,” the analyzed version of the print, you can also retrieve the image of a fingerprint and even pull raw images from the optical sensor! This is the updated version of the GT-511 which has an increased memory capacity. The module can store up to 200 different fingerprints (that’s 10x more than the old version!) and is now capable of 360° recognition. The module is small and easy to mount using two mounting tabs on the side of the sensor. The on-board JST-SH connector has four signals: Vcc, GND, Tx, Rx. A compatible JST-SH pigtail can be found in the related items below. Demo software for PC is available in the documents below, simply connect the module to your computer using an FTDI Breakout and start the software to read fingerprints! Note: The module does not come with a cable, if you do not have a 4-wire JST-SH pigtail, you can add PRT-10359 to your cart, or check in the Recommended Products section below.
