介绍了基于EM78P447SB单片机、集成湿度传感器、亮度传感器、钟控开关和自制光电耦合器制作的积木式霓虹灯控制系统。
Introduced the application of humidity and brightness sensor in neon light controller system based on EM78P447SB micro-chip computer.
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.
传感器按需轮换屏幕背景，从肖像画到风景图，简单易行；在用户接听电话时关闭背景以节约用电；并且根据周围光线调整背景亮度。
Sensors rotate the display from portrait to landscape as required, turn off the display to conserve power when a user lifts the phone to his ear and adjusts its brightness according to the light.
无线传感器也正突然出现在农田里，用以在广阔的土地上测量温度、湿度和亮度，在这里有线传感器铺设起来很费力气。
Wireless sensors are also cropping up on farms, to measure temperature, moisture and light on tracts of land where wired sensors cannot easily go.
运行中如果左侧的传感器感应的亮度比右侧的强，那么就会通知的你的差分驱动器向左转。
If the sensor on the left see's more light than the one on the right, tell your differential drive to turn left. If they see the same amount of light, tell your robot to drive straight.
对于宽波段传感器，不一定能直接由普朗克定律或者斯蒂芬玻尔兹曼定律建立温度与辐射亮度的关系。
It is not always suitable to use Planck's law or Stefan-Boltzmann's law to describe the relation between brightness temperature and radiance for a wide band sensor.
本实用新型公开了一种数码相机，该数码相机包括一个闪光灯，一个发出表示接近数码相机环境光亮度的信号的环境光传感器，和一个闪光灯控制器。
A digital camera includes a photoflash lamp, an ambient light sensor generating a signal representative of an ambient light level proximate the digital camera, and a photoflash controller.
