Abstract
In order to overcome the single sensor detection in complex environment in the fire alarm, false positives,false negative phenomenon, system based on the digital temperature sensor DS18B20 and smoke ion MQ 2 sensor as the fire detector,STC89C52 single chip as the control core, design a set of simple and practical,strong anti interference ability of the fire alarm system,the hardware of the system adopts modular structure, software the design for the use of smoke density rating system,the temperature detection range limits.关键词
