1、 毕业设计（论文） 题 目 基于 Zigbee 的室内空气质量检测仪设计 学 院 通信与电子工程学院 专业班级 通信工程 111 班 2015 年 6 月 25 日 I 摘 要 随着科技发展，空气污染严重影响了人们的健康。因此，为家人和朋友创建一个空 气新鲜、健康舒适的生活环境是非常必要的。室内空气质量检测是刚兴起的一个行业。 该行业是通过对室内的装修、家具污染引起的环境污染物超标所进行检测和分析过程， 并且出具国家权威的、法律效力的检测报告。通过检测报告我们可以判定室内各种污染 物质的浓度，然后进行针对性的防控。 本设计是由传感器、Zigbee 模块和上位机搭建一个基于 Zigbee 无线传

2、感网络的室 内空气质量检测仪。第一步，通过各种传感器对室内甲醛、苯、氨气、总挥发性有机物 TVOC 等空气污染物进行检测和数据处理； 第二步， 将检测参数传送给 Zigbee 终端节点； 第三步， 通过 Zigbee 无线传感网络将接收的数据传送到主控端进行空气质量指标的显示 和监控。如果检测到某些空气污染物超标的话，就会发出报警来提醒用户采取相应的措 施。室内空气质量检测仪采用 Zigbee 的无线传感技术，可以进行多点检测，还可以方便 的添加和移除 Zigbee 节点，具有成本低、组网灵活、简单易用等优点。不仅适用于新房 入住和刚装修完的房子的空气质量检测，也可以对室内空气质量进行实时检测

Therefore, it is necessary to create a fresh air, healthy and comfortable living environment for our family and friends. Indoor air qua

4、lity detection is a newly rising industry. The industry will give a air pollution detection, which through detecting pollution caused by the indoor decoration, furniture and so on. It issued a national authority and legal detection report. Through the detection report, we can see the concentration o

5、f indoor pollution substances, and then take some measures to prevent the pollution. The air quality detector is consist of a sensor, Zigbee module and PC, which is based on a wireless sensor network of Zigbee to detect indoor air quality. The first step is collect data, which though a variety of se

6、nsors of indoor formaldehyde, such as benzene, ammonia, total volatile organic compound TVOC and other air pollutants sensors. The second step is data transmission, which transport the test parameters to the Zigbee terminal node. The third step, the main control end display and monitor the air quality index, which will receive the number through the Zigbee wireless sensor network. If the detection of certain air pollutants exceed the standard, It will alarm to remind
