Abstract：Fireisamajordisasterthatthreatens socialsecurityand poses aserious threattothesafetyof people's lives andpropertyforalong time.With theaccelerationofurbanizationandthecomplexityofbuildingstructures，thelimitations oftraditionalfre alarm systems interms ofresponse speed，monitoringaccuracyand intellgence have become increasingly prominent，anditisdifcult tomeet theneedsofmodernsafetyprotection.Intispaper，anintellgentfirealamsystemis designed based on STM32F103C8T6 microcontroller.The smoke concentration， temperature and humidity and CO2 dataare monitoredinrealtimebyMQ-2，DHTandSGP30sensors.Thesystemautomaticallyegulatesairconditioners，fnsandother equipmentaccording tothepresetthreshold，and triggers localsoundand lightalarms incaseofdanger.TheOLEDdisplay scren isused todisplaytheenvironmental parameters inreal time，andthebutonswitching manual orautomaticmodeand thresholdsetingaresupported，whichsignificantlyimprovesthereal-time monitoringandcontrolfexibilityExperimentssow thatthe systemhasfastresponseandstableoperation，whichprovides aneffcientandreliablesolution for fire preventionand control， and has a wide application prospect.
