摘要
空气环境质量一直备受人们的关注,如温度、湿度和PM2.5浓度,这是评价某个地方空气环境质量好坏的常用标准之一。为了满足对室内空气环境质量的实时监控,文中设计了一种基于单片机的室内空气质量实时监测系统,其以C51单片机为控制核心,使用温湿度传感器和PM2.5固体颗粒物传感器采集周围环境空气样本数据,并将其作为单片机输入信号,经由单片机处理后,在液晶显示屏上显示各种数据值。另作,使用红外、光敏和WIFI传感器,增加了该系统的扩展性,实现了夜间息屏和连网操作。最终调试表明,该系统性能良好、操纵简单、实用性较强,还具有成本低、外观小巧、测量结果值准确的优势,具有更好的应用前景。
Air environment quality has always attracted people's attention,such as temperature,humidity and PM2.5 concentration,which is one of the common standards for evaluating the quality of air environment in a certain place.In order to meet the real-time monitoring of indoor air environment quality,this paper designs a real-time monitoring system for indoor air quality based on a single-chip microcomputer.It takes the C51 single-chip microcomputer as the control core,uses temperature and humidity sensors and PM2.5 solid particle sensors to collect ambient air sample data,and uses it as the input signal of the single-chip microcomputer.After being processed by the single-chip microcomputer,various data values are displayed on the LCD screen.In addition,the use of infrared,photosensitive and WIFI sensors increases the scalability of the system,and realizes night screen rest and networking operations.The final debugging shows that the system has good performance,simple operation and strong practicability.It also has the advantages of low cost,small appearance and accurate measurement results,and has better application prospects.
