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.

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.
