摘　　要：大气环境中可吸入颗粒物(PM2.5)的实时监测是评价大气颗粒物的重要指标之一.基于物联网技术开发了PM2.5浓度检测系统.采用光散射法的PM2.5传感器获得大气环境中的PM2.5浓度值.传感器通过WiFi无线技术与网络路由器(WiFi热点)连接,网络路由器通过3G/4G移动网络与远程嵌入式ARM-Linux服务器连接.服务器基于C/S(客户端/服务器)模式实现了计算机与移动设备实时数据的查询.实验结果表明,该系统具有巡检时间短(20s)、自组织、多节点、灵敏度高等优点.The real-time monitor of the inhalable particulate matter（PM2.5）is one of the significant indexes in atmospheric environment.The PM2.5particle concentration monitoring system is developed based on the internet of things.The PM2.5concentration is acquired by using the PM2.5sensor which is on the basis of the light scatter.The sensor node is connected to the network router（WiFi Hotspot）by using the wireless technique of the WiFi meanwhile the network router is linked to the remote embedded ARM-Linux server using 3G/4G mobile net.The real-time data query of the personal computer and mobile device is achieved with the help of the Client/Server framework.The experimental results showed that the system has the advantages of short inspection time,multi-node,high sensibility,and so on.
