產(chǎn)品概述
IIC顏色傳感器使用TCS34725顏色傳感器進(jìn)行顏色識(shí)別。TCS34725是一款高性價(jià)比的RGB全彩顏色識(shí)別傳感器，傳感器通過光學(xué)感應(yīng)來識(shí)別物體的表面顏色。支持紅、綠、藍(lán)(RGB)三基色，支持明光感應(yīng)，可以輸出對(duì)應(yīng)的具體數(shù)值，幫助您還原顏色本真。
為了提高精度，防止周邊環(huán)境干擾，我們?cè)趥鞲衅魃咸砑恿艘粋€(gè)鏡頭罩，有效減少外界雜光干擾傳感器，讓顏色管理更加準(zhǔn)確。板載自帶2個(gè)高亮LED，可以讓傳感器在低環(huán)境光的情況下依然能夠正常使用，實(shí)現(xiàn)“補(bǔ)光”的功能。模塊采用I2C通信，擁有4P防插反接口，更加便利。
