求翻译：随着传感器技术、微处理器技术和信号处理技术的飞速发展，烟雾报警器已经成为火灾自动探测技术的发展方向，扮演着一个越来越重要的角色，它对人们的生活具有很大的影响。“烟雾报警器”是由两个部分组成：一是一台用于检测烟雾的感应传感器，二是一只声音非常响亮的电子扬声器，一旦发生危险可以及时警醒人们。当今，世界上使用得最为普遍的烟雾报警器当属光电式烟雾报警器和电离式烟雾报警器。 而本次设计主要是通过传感器对烟雾的感应使二极管接到信号依次点亮，达到预期效果，同时使自己对其基本知识进一步了解以便在生活中的应用。是什么意思？

As microprocessor technology, sensor technology and signal processing, and the rapid pace of technology development has become a smoke alarm, automatic fire detection technologies, plays a more and more important role, in people's lives have a large impact. The "Smoke Alarm" is made up of two parts:
