摘　　要：利用单片机实现空气中PM2.5及甲烷值的检测。选用了STC51单片机,制成的一个简单便携的空气质量检测系统,实现对空气中甲烷(CH4)和PM2.5(粉尘浓度)的检测,检测结果在LCD1602显示,当检测值超出标准值时峰鸣警报。设备完成软、硬件调试后能够实时测到甲烷及PM2.5的值,结果达到设计要求。Detection of PM2.5 and methane in air by using single chip microcomputer. A simple and portable air quality testing system based on STC 51 microcomputer is used to detect air methane ( CH4 ) and PM 2.5 dust concentration detection, test results in the LCD1602 show that when the detection value exceeds the standard value ,the alarm will sound. After the equipment is debugged the value of methane andPM2.5can be measured in real time, and the result meets the design requirements.
