In order to solve the traditional electrical fire monitoring system alarm is not timely.An early warning system of electric fire based on electronic nose technology is designed.The system hardware is composed of sensor array composed of several gas sensors and intelligent control unit with STM32L071 single chip microcomputer as the core,which can monitor the early environment of electrical fire and transmit data.The method of fuzzy theory and AHP is used to realize multi-sensor information fusion and reduce the rate of false positives.The experimental results show that the designed early warning system can accurately reflect the environmental characteristics and re-alize the early warning of electrical fire.
