基于单片机的智能电子鼻的设计

ABSTRACTIn the 21st century,our people's life has also entered a well-off society.With the improvement ofliving standards,I chose some common life gases in my graduation project,among which Highthreat to human lifeThe intelligent electronic nose system is based on STM32 single chip microcomputer,whichfully expands the air quality detection module PM2.5,the gas poisoning prevention modulePM2.5 and For air quality,the sensor first detects the PM2.5 concentration in the air.The resultshows that if the detection value prevents carbon monoxide poisoning,the carbon dioxideconcentration in the detection unit Air sensor,if the result is higher than the normal value,on theone hand,the single chip microcomputer controls the stepping motor automatic alarm module,the sensor Smoke concentration detector,if the detection result is higher than the normal value,the buzzer will give an alarm,if the buzzer button is pressed.KEY WORDS:STM32 single chip microcomputer Sensors,GSM short message alarm
