Open publisher page 0 citations

Abstract

With the increasingly requirement of living standard, people have great demand for alarm system. The traditional electric-alarm devices have developed to digital intelligent ones with the rapid development. The design is a small alarm system using C51 microcontroller control, and some of the peripheral circuit. The system uses 89C51 as microprocessor, including detecting module, MCU processing module and voice processing module. This kind of alarm system is intelligent controlled and can be used in different places.
