In desperate need of a user oriented to ordinary families, cost-effective and reliable operation, may refuse illegal invaders in the outdoors intelligent anti-theft alarm system to replace burglary-resisting door and dooryard. So this design goal is to find a suitable for ordinary family security systems. This intelligent security control system application design method and general anti-theft system is different, this system USES a ultrasonic range-finding sensors and MCU combination, including ultrasonic range-finding sensors to provide alarm signal approach to make the low cost and easy maintenance, probe small, can put in hidden place and will not be discovered, accept signal sensitive, therefore has the obvious advantages and prospect. This design is for intelligent security control system design and research. Initially find information, produce the overall design thoughts, then draw principle diagram, welding hardware and software and hardware debugg
