產(chǎn)品概述
IIC觸摸傳感器是 12 路電容式觸摸傳感器，基于接近電容式觸摸傳感器控制器的飛思卡爾- mpr121 芯片。它檢測(cè)到人類手指的觸摸或接近?？梢耘c Arduino 簡(jiǎn)單連接，創(chuàng)作你的互動(dòng)項(xiàng)目。電容式觸摸傳感器可通過檢測(cè)當(dāng)一個(gè)人（或動(dòng)物）接觸到的傳感器電極之一輸出不同的信號(hào)給控制器。IIC觸摸傳感器可能應(yīng)用于之前我們用過的使用觸碰感知的設(shè)備上，如觸摸式平板電腦和手機(jī)，以及觸控面板的電器。該IIC觸摸傳感器允許您用在可以對(duì)人體的接觸作出反應(yīng)的電子產(chǎn)品中，并且支持最多 12 個(gè)獨(dú)立的觸摸通道。觸摸電極有時(shí)也能感知到手指的非直接接觸，那就是說，你不需要用你的手指觸摸的觸角上。
