摘要
针对目前严重的空气质量问题,文中介绍一种基于STC12C5A60S2的空气质量检测系统,系统以STC12C5A60S2单片机为控制器,能够实现周围环境中粉尘颗粒物浓度测量,SO2、NO2、CO三大主要污染气体的浓度测量以及环境温度、湿度的测量,并在LCD上显示出来,最后将测量结果通过无线发送出去,从而实现多项空气质量指标的检测。文章主要介绍了整体系统结构、各传感器特性、各功能模块电路设计以及系统工作的程序流程。经过实验,系统可以实现对空气质量的全面、准确测量。
According to the terrible problem of air,this paper introduces the air quality monitoring system based on STC12C5A60S2.The chip STC12C5A60S2 was used as the chontrollor.The system can realize the following functions, such as the detection of air temperature and humidity, SO2 concentration, NO2 concentration, CO concentration, and the level of particles. At the same time, it also has a function of display and transport the messeage to the center of control. The design of hardware and software, the choice of components, and the design of unit circuits and the circuit connection of the system are described. Through the experiment, it can monitor the quanlity of air precisely and comprehensive.
