基于STM32的室内空气质量检测系统设计

Design of indoor air quality testing system based on STM32

以STM32单片机为控制中心,运用多种传感器,设计了集室内空气质量检测、显示与报警功能的空气质量检测系统。该系统利用传感器对空气中的PM2.5、有害气体、空气温湿度等多种参数进行检测,通过WiFi模块将数据上传到手机等移动设备,空气质量达到警戒线时将触发系统报警。该系统可靠性高、成本低,检测方便快捷。

A kind of air quality monitoring system is designed , using STM32 microcontroller as the control center, using a variety of sensors, able to complete on indoor air quality testing, display and alarm is designed. The system uses sensors to detect the PM2.5 in the air, harmful gas, air temperature and humidity and other parameters, through the WiFi module to upload data to mobile devices such as mobile phones. When the air quality is serious to a certain extent, the alarm system will be triggered. The system has high reliability and low cost, and it provides a convenient and rapid detection system for air quality.
