傳感器LTR-558ALS-01光寶 紅外+接收+光感 三合一光距離傳感器

智能機(jī)的時(shí)代已經(jīng)來臨了，中國市場(chǎng)已經(jīng)成為智能手機(jī)的紅海，作為配套器件的我們，緊跟手機(jī)業(yè)變化的節(jié)奏，
我們特別推薦此款器件
能機(jī)的大屏對(duì)電池的續(xù)航能力的苛刻要求，光寶特意開發(fā)出這款控制IC，
LTR-558ALS-01
光寶專為智能3G手機(jī)特別是全觸摸屏手機(jī)，專案研發(fā)出一系列的I2C光接近傳感器，LTR-558ALS-01三合一距離傳感器是(IRLED + ALS + PROXIMITY)并在一起。好處是把發(fā)射LED的公差減至最低，同時(shí)有高感度偵測(cè)環(huán)境光功能。其主要功能在于根據(jù)環(huán)境光調(diào)節(jié)背光亮度，手機(jī)在通話狀態(tài)下靠近人臉時(shí)關(guān)閉背光，并且能防止通話中手指頭誤觸屏摸，而導(dǎo)致操作失誤。
該型號(hào)傳感器具有耗能低，兼容性強(qiáng)，可兼容任何手機(jī)軟件平臺(tái)，設(shè)計(jì)簡(jiǎn)便等特點(diǎn)。
