Design of a Multi Sensor Security Alarm System in Home Safe Based on MSP430 Chip

A home safe surveillance system was designed based on the MSP430G2553 microcontroller and multi sensor. This system was designed with the multi modules method, and mainly includes a power control module, signal processing module, multi sensor module, keyboard control module, liquid crystal display module and an alarm output module. The sensor module using the extensible design mode, and the alarm output module using the hierarchical design mode, it is convenient for the needs of different users. According to the environment of the system＇s actual used, the system has a strong of its own security monitoring, such as dual power supply mode, the system vibration monitoring, the emergency alarm output, and the alarm module explosion-proof design mode. All of this can make the system security effectively, and make it send the alarm information in the first time. The experimental results show that the system has a good stability and reliability, achieve the requirement of actual use.
