摘要
甲醛是室内空气污染最主要的污染源,目前市面上甲醛检测仪存在检测周期长、操作复杂、成本高等不足。为此,设计了一款适合家用的甲醛检测仪,以满足居民对室内空气质量检测的需求。该设计基于低功耗的主控芯片STM32微控制器,利用传感器检测技术对室内的温度、湿度和甲醛浓度进行实时检测和显示。当室内空气中的甲醛含量达到警戒值时会触发报警,同时将检测到的数据通过无线模块发送至智能终端。该检测仪具有操作方便、实时检测、功耗低等优点。
Formaldehyde is the main source of indoor air pollution.The formaldehyde detector on the market has some disadvantages such as long detection period,complicated to operate and high cost.Therefore,a household formaldehyde detector is designed to meet the needs of residents to monitor the indoor air quality.The design is based on STM32 microcontroller with low power consumption,and uses sensor detection technology to detect and display indoor temperature,humidity and formaldehyde concentration in real time.When the indoor formaldehyde concentration exceeds the alarm value,the detector will trigger the alarm,and meanwhile send the measured data to intelligent terminal by wireless module.The detector has advantages of easy operation,real-time detection and low power consumption.
