室内的空气质量直接关系到人体的健康,而二氧化碳的浓度是影响空气质量的一个主要因素。传统的检测系统存在成本较高、移动性差、安装维护困难等缺点,该文提出了一种基于无线传感器网络节点的二氧化碳浓度检测的方法。利用节点的UART口与二氧化碳传感器模块相连,实现对二氧化碳浓度的数据采集,该方法具有低成本、移动性好、组网灵活等特点。
Indoor air quality is directly related to human health,in which the concentration of carbon dioxide is one of the major factors.Some existing concentration of carbon dioxide acquisition technologies are high cost,poor mobility,difficulty to install and maintenance,this paper presents a new approach of collecting the concentration of carbon dioxide by wireless sensor nodes.Data acquisition from carbon dioxide sensor by connecting it with node through UART interface,this method is low cost,good mobility and network flexibility.
