说到传感器，我们发现一个亮度自动调节的问题，在日光下屏幕亮度自动调节正常，但在暗环境中屏幕会自动变得过于昏暗。

Speaking of sensors, we experienced problems with the auto-brightness setting, which would dim the screen too much in low light, while behaving normally in daylight.

但是在明亮的环境下使用昏暗的屏幕是非常难受的，所以大多数手机都提供自动亮度调节模式，可以根据周围环境的亮度自动调节屏幕亮度。

But it's tough to use a dim screen in bright environments, so most phones offer an auto-brightness mode that automatically adjusts the screen's brightness based on ambient light.

其中，有日光感应装置和人在场感应装置的灯具，可以自动调节灯具的亮度以达到节能的目的。

You can have a look yourself, we used energy saving lights with sensors that measure the daylight and the movement of people.
