Microcontroller through the infrared sensor part and the voice-activated sensor part of the coming changes in the signal to determine whether there are outsiders, if sent through the speakers or the diode to the police; infrared sensors, infrared emission through the launch tube to the receiving tube, two between elements of a connecting via infrared, when there are objects stand in the middle, they then pass on the changes in level microcontroller; Similarly, voice-activated sensor is converted into electrical signals into acoustic signals and then transmitted to the microcontroller; keyboard is used to set the alarm trigger conditions.

单片机通过红外传感部分和声控传感部分的传来的信号的变化来判断是否有外来者，如有则通过扬声器或者发给二极管来报警；红外传感器是通过发射管发射红外线到接收管，两个元件之间通过红外线进行连接，当有物体挡在中间时，便把电平的变化传给单片机；同理，声控传感器是把声音信号转换为电信号然后传送给单片机；键盘是用来设置报警触发的条件。
