Description: Fire is a kind of high frequency, destructive disasters, which was given a strong attention. In this paper, based on the development of sensor technology and computer technology, starting the security problem that people increasingly serious, smart fire alarm was designed based on single chip microcomputer system.The designed system is suitable for the residents of housing. The system employs a temperature detector and smoke detector to detect fire together they can give a more accurate alarm and reduce the false alarm rate. Using AT89S52 as controller, the temperature sensor and smoke sensor are employed to acquired the fire signal. After the signal was processed and A/D conversion it was in put the SCM. Then the data was processed by the SCM, Comparing with the preset value and determining whether it exceeds the alarm limit or not. In normal condition four 7-segment LEDs shows the smoke concentration and temperature. When it fire, the designed system gives light and sound to alarm p
