摘要
本位介绍了光敏声光报警器的制作过程,以及光敏声光报警器在生活中的应用,国内为对于光敏声光报警器的研究。
光敏学是一门高度交叉的综合学科,它广泛涉及电学、物理学、计算机学、自动控制功能等多个领域,在当今世界有很好的发展前景。
光敏声光报警器是光敏研究领域的杰出代表。它具有体积小,制作简单,零件易找的优点。当光线较亮时光敏电阻阻值减小,致使流入蜂鸣器的电流增大到其额定电流时,蜂鸣器开始鸣响报警。所以常用于存放贵重物品的保险柜,塑料大棚对光照的控制等等。与其他报警器相比,光敏声光报警器就有很多优点,比如说自动性强、灵敏度高、体积小、便于安装。不仅如此,从技术发展的角度考虑,光敏报警器的研究将会对传统的机械结构、控制方式产生深远影响,并将极大地促进光敏学的研究和应用,使人类更好地运用光敏学。

Abstract
Standard introduced the making process of the photosensitive sound and light alarm, and photosensitive sound and light alarm in the life, the application of domestic investigations of the photosensitive sound and light alarm.
Photosensitive learning is a highly prehensive discipline, it is widely involved in electrical, physics, computer science, automatic control function, and other fields, in today's world there are good prospects for development.
Photosensitive sound and light alarm is photosensitive prominent representative in the field of study. It has small size, easy fabrication, easy to find advantages. When the light is bright the photosensitive resistance value decreases, and the current increases to its rated current flowing into the buzzer when the buzzer began ringing alarm. So we often used to deposit valuables in the safe, the plastic greenhouses for light control and so on. Compared with other alarm, photosensitive sound and light alarm system has many advantages, such as strong automaticity, high sensitivity, small volume, easy to install. Not only that, but from technological development perspective, photosensitive alarm research will be to the traditional way of mechanical structure, control have a profound impact, and will greatly promote the photosensitive learning research and application, make better use of human light of learning.
