摘要物联网在全世界范围掀起了热潮，许多国家也将其列入国家战略规划中。在物联 网发展的大背景下，温湿度监测系统的研究也逐渐深入，各种新兴的技术被运用在系 统设计中。
本文以计算机机房为监测对象，设计了一套以物联网思想为基础的智能化程度较 高的温湿度监测系统。基于物联网的三个层次，将系统分为四个模块，提出了总体设 计方案后，进行分模块设计。首先针对机房对温湿度的要求，选定 DHT11 温湿度传 感器，并连接 Arduino 微控制器完成数据采集，其次使用 XBee 无线模块，搭建基于 ZigBee 无线通信协议的星型数据通信网络，来实现节点间的数据传输，然后建立以 Tomcat 为服务器的数据处理中心，对数据进行计算和存储，最后设计手机端界面，并 以 swift 语言为基础完成 iOS 手机端 App 的开发，数据连通后，可通过手机端的交互 完成对室内温湿度的实时监测。83989
本论文以一特定环境为例来说明系统的设置，在拥有整套系统的构架后，实际可 应用的场合广泛，如温室大棚、图书馆、酒窖、家居室内等。整个系统有着能耗低、 可视化界面友好的优点，实现软件与硬件的结合、无线通信和云端数据处理，且与移 动手机端相连接，使得监测过程更加方便快捷。

Abstract The Internet of things caused a boom in many countries around the world,and it has been listed in their strategic planning 。 In the context of the Internet of things’ development, the research of temperature and humidity monitoring system is also gradually proceeding, all kinds of emerging technology is applied in system design。
Aimed at computer room monitoring, this paper designed a set of highly intelligent temperature and humidity monitoring system based on IOT thought。 And the system is pided into four modules, in view of the three levels of Internet of things。 Then it put forward the overall design and the module design。 Firstly, it selected DHT11 temperature and humidity sensors, base on the requirement of the room’s temperature and humidity, and connected the Arduino microcontroller to complete data collection。 Secondly, it used XBee wireless module to set up data communication network based on Zigbee wireless communication protocol of the star, so as to achieve data transmission among nodes。And then it established a data processing center with Tomcat for the server, so as to compute and storage data。 Finally it designed the mobile terminal interface, and completed iOS mobile terminal App’s development on the basis of swift language。 The data connected, it can complete the real time monitoring of indoor temperature and humidity through the interaction on mobile phones。
This paper illustrate the system Settings in a specific environment, and it is widely applicable in many occasions such as greenhouses, library, wine cellar, home interior, etc, with the whole framework of system。 The whole system has the advantages of low energy consumption and friendly visual interface, and it’s supposed to achieve the combination of software and hardware, wireless communication and cloud data processing。 The last but not the least, it connected to the mobile phone, which made the monitoring process more convenient and quick。
