The Application of MCU for Security Alarm System of Home
Abstract
Lesson a safety on aiming at current community safety more and more ising concern by people, particularly is living quarters with report to the police and even is ten thousand with thousand related, put forward a kind of community that pass the telephone net constitute the peaceful defending the system. Its terminal is a community service center, the head is a living quarters safety to report to the police the system.

Another circumstance is host not at living quarters, then be proceeded by microcontroller the emulation take off the machine with stir the number, being started by microcontroller to record in advance the speech in microcontrol chip proceed to report to the police.

Like this the expenses of the system is not much, installing the construction measures not very, since can the artificial report to the police to can report to the police automatically again, can satisfy the safe request in living quarters.
