The TSM3401CX is an ambient light sensor developed by ams (formerly TAOS Inc.). It’s designed to detect and measure the ambient light levels in its surroundings. This sensor typically provides analog output proportional to the intensity of the light falling on its surface. It finds applications in various devices and systems where automatic adjustment of screen brightness, backlight control, or ambient light monitoring is necessary, such as in smartphones, tablets, laptops, and other display-equipped devices.
