摘　　要：日常家庭生活中,经常容易出现的失火、盗窃现象,考虑设计一种玻璃破碎报警器件,来提高安全防护的效果.通过选用压电式传感器MPX4115A来感应外界信号的变化,将感应信号传递给单片机控制系统,最终的信号以蜂鸣和光闪两个方面来实现较好的报警效果.In this article,a device that can improve the safety and the protection was designed.it is aimed to conditions that fire disaster and stealing occurred in our everyday life.At first,the piezoelectric sensor MPX4115A was used to response the change of outer signal.Then,the output of the MPX4115A will be transferred to the singel-chip controlling system.At the end,the alarming effect will be realized by buzzer and LED.
