the principles and structures of the pyroelectric sensor and the photosensitive sensor, as well as their application in commercial office building were introduced.
介绍了热释电传感器和光敏传感器的原理和结构,以及它们在商务办公楼中的应用。
so, the pyroelectric sensor that is located on the moving track of the infrared focus is scanned by the infrared focus signal continuously and generates the autonomous sampling pyroelectric signal.
这样,安装在红外光焦点运动轨迹上的热释电敏感元件被红外光焦点不断扫描而产生自主采样的热释电信号。
the traditional pyroelectric sensor (or a sound sensor) and the combination of light source, without reserve electric wire, place the product directly on the lamp and turn on the power.
