摘要
为了对环境空气中的粉尘浓度进行方便快速而准确的检测,基于STC89S52RC单片机设计了一种粉尘浓度检测系统。该系统采用基于光散射原理的粉尘传感器采集信号,使用1.3英寸OLED显示模块进行显示,应用C++进行软件设计,实现了PM2.5及PM10的实时检测与显示,并设计了声光警报系统,当检测到的数据达到设定的阈值时,便会触发警报。调试结果表明,该系统测量准确,运行稳定可靠。
In order to quickly and accurately measure the concentration of dust in the air, a dust concentration detection system was designed based on STC89S52RC MCU. The system uses a light scattering type dust sensor to collect signals, a 1.3-inch OLED module to display information, and C ＋＋ to design software. The real-time detection and display of PM2.5 and PM10 were realized. In addition, a sound and light alarm system was designed. If the detection values exceed the set threshold, a system alarm will be triggered. The system debugging result indicates that the measurement is accurate, stable and reliable.
