【摘要】 针对传统的PM2.5空气质量监测系统体积大、成本高,造成系统覆盖面较小并且实时性不好等问题,提出了基于Arudino、W5100和乐联网的实时监测PM2.5浓度值的方案。重点描述了监测终端的硬件结构与软件设计,并对系统的工作流程及乐联网的配置进行了介绍。实验结果验证了该系统应用于PM2.5实时监测的正确性及可行性,具有性能稳定可靠、经济高效等优点。更多还原

【Abstract】 To overcome the demerits of traditional PM2. 5 air quality monitoring system,e. g.,bulky,high cost,smaller system coverage,and poor real time performance,etc.,the scheme based on Arudino W5100 and Lewei 50 network for monitoring PM2. 5 in real time is proposed.The hardware structure and software design of the monitoring terminal are described emphatically,the work flow of the system and the configuration of Lewei 50 network are introduced. The experimental results verify the correctness and feasibility of the system applying in real time monitoring of PM2. 5; it possesses stable and reliable performance and higher economical effects.更多还原
