Abstract：This design using MSP430 microcontroller as dormitory intelligent security fire alarm system control core, match with dc power supply, wireless transmission, sound-light alarm, external storage, smoke detection, human testing, inspection, the keyboard, the valuables display outside circuit, and the intelligence, automatic monitoring dormitory function. By monitoring dormitory pyroelectricity sensor, smoke sensor buzzer and LED to realize human testing, smoke detection audible and visual alarm function, Choose 4 * 4 matrix keyboard input password system's warnings, Using photoelectric switch records in the dormitory and staff; Choose ISD4002 speech hint lock function realization circuit, NRF905 and realize remote monitoring, wireless transmission can always check the current or the dormitory security situation in recent days, Using radio frequency transmission and asynchronous communication network monitoring, Choose sound magnetic security system in detecting the valuables. The design of low cost, low power consumption, the successful completion of the subject and the basic requirements.
