摘要随着我国改革开放的逐步深入，经济和社会得到了突发猛进的发展，与此同时人们越来越关注污染程度日益严重的居住环境，开始利用高科技产品及时对居住环境进行检测，从而及时了解环境状况。伴随着单片机技术的飞速发展，通过单片机开发的检测仪器越来越小型化和多样化，因此采用单片机技术设计一款小型的对空气质量监测的PM2.5测量设计具有重要的意义。
本文主要介绍了基于单片机的空气质量PM2.5测量设计系统。该系统把单片机的控制技术和传感器技术相结合，实现对空气颗粒大小的采集。采集的数值经过模数转换，再传输给单片机，经过单片机的计算后，在液晶显示屏显示。该设计对检测空气质量，提高人们的生活质量，促使人们改善环境，提高身体健康，具有重要的意义，因此应用前景非常广泛。30869

Based on the air purifier PM2.5 detection module software development
Abstract With the gradual deepening of reform and opening up, economic and social development unexpected, at the same time, more and more people pay attention to increasingly serious pollution of the living environment. Began to use high-tech products timely on the living environment of detection, so as to understand the state of the environment in a timely manner. With the rapid development of MCU, through the MCU development testing instrument is more and more small and persified, so using SCM technology is of great significance to design a small on air quality monitoring of PM2.5 measurement design.
This paper mainly introduces the design of PM2.5 air quality measuring system based on single chip microcomputer. The sensor technology and the control technology of MCU , the air particle size of collection. The collected data through analog to digital conversion, and then transmitted to the MCU, through the MCU calculation, in the LCD display. The design of the air quality testing, improving the quality of life of people, encourage people to improve the environment, improve the health of the body, is of great significance, therefore very broad application prospects.
