【Abstract】To effectively prevent fatal accidents caused by heat stroke in vehicles，this paper designs an intelligent active protection system for the in-vehicle environment.This system takes the STM32 single-chip microcomputer as thecore controllrand integrates high-precision digital temperatureand humiditysensors，SGP30 semiconductor gas-sensitive elements，SY1B carbon monoxide sensors and infrared human body sensing sensors， which are used forreal-time collection ofenvironmental parameters.Atthedata transmission layer，the GSM module is usedto synchronouslypushthe monitoring data to the user's mobilephoneAPPand the cloud management platform， ensuringthat thereareno blindspots in remote monitoring.When abnormal environmentalparameters aredetected， the system will automatically triggeranaudible and visual alarm.Through the linkage mechanism of real-time environmental perception and inteligentearly warning，the system significantly enhances the safety guaranteelevel of the in-vehicle environment，builds asolid defense line againstlife and health issues suchas children’ssuffocation in vehicles，and promotes the development of the active safety protection system towards intelligence.
