室内环境检测器的设计 摘要 对于室内环境而言，主要指人类在室内活动所需要的场所，并且伴随人类 的活动不断延伸和拓宽，而且渐渐变成了互相融入结合为整体的环境。并且， 在当今的社会中，人类和环境之间的关系受到广泛的关注。室内环境检测也逐 步走进我们的今天。而以往的传统的室内环境检测系统多数为有线方式，这种 方式需要大量布线，影响室内美观，造成了资源浪费，如果线路老化发生了问 题，修理也造成了不便。 本文设计了一种室内环境检测系统，克服了传统方式的局限性，具有不破 坏居室原有结构，连接线路数量少、布线简单，可以灵活安装，同时采用低功 耗设计，节能等优点。 关键词： 室内环境 室内环境检测器 室内环境检测系统 Design of indoor environment detector ABSTRACT The indoor environment is the place which provides for the peoples indoor activity, it expands with the peoples life, and gradually develops into the mutually permeable and indivisible environmental whole, in the human society today, People pay more and more attention to the relationship between human and environment. Indoor environment inspection also step by step into our today. The traditional indoor environment detection system is mostly wired, which needs a large number of wiring, which affects the beauty of the room, resulting in a waste of resources. If the line aging problems, repair caused inconvenience. In this paper, an indoor environment detection system is designed, which overcomes the limitation of the traditional method and has the advantages of not destroying the original structure of the room, less connecting lines, simple wiring, flexible installation, low power design, energy saving, and so on.
