• 产品概述

    MT3212 is a highly sensitive wide dynamic range digital ambient light sensor (ALS) with a low-profile and small footprint. 

    It includes Red, Green, Blue, Clear and Flicker photodiodes, which provide ambient light, temperature color and flicker frequency information of the ambient light source. 

    MT3212 architecture accurately measures the ambient light and enables the calculation of irradiance of different light sources. This provides ultra-high sensitivity for luminance detection and very useful for smart lighting management, especially in robust backlight brightness, display appearance, camera color temperature and flicker control.
