By using microcontroller can effectively solve the sensor with sensitivity and alarm accuracy, the conflict between can achieve the desired effect. This design has high reliability characteristics such as low misstatement rate, there is certain practical value. This paper discusses the meaning of the topic selection, design ideas, the component selection, system hardware and software debugging. First, it introduces that the fire bring us the impact of daily life and introduces the development of the fire alarm system; Then, this paper introduces a kind of multisensor fire alarm system design project; Then explains the function module system hardware and software design, Hardware including the selection of SCM and sensor, various circuit module design software design of the sensor for SCM and include data acquisition, system detection and alarm program design; After a brief for hardware debugging, to conduct some analysis debugging results; Final
