摘要
当前人们的居住环境空气质量越来越差，当前在大部分的用户中，并没有实时准确检测大量空气质量的检测仪器，此次设计为了解决这个问题，设计一款空气质量检测系统，该系统分为软件设计和硬件设计，硬件设计包括：MQ-2烟雾检测传感器检测环境中的烟雾浓度，MQ-5检测当前环境中的天然气火灾煤气，MQ-7检测环境中的CO浓度，MQ-135检测当前环境中的有害气体浓度，OLED将检测的数据进行显示，当检测到气体的浓度异常时，进行声光报警，并控制风扇和净化器的工作，使得空气中的环境处于正常的范围，蓝牙监测模块，将监测的数据传输到用户手机上，用户也可以通过手机远程控制通风或者净化器的工作，及其控制模式的切换；软件设计，此次设计采用Kil5作为此次设计的程序编程软件；通过软件和硬件配合使用，经过调试，此次设计可以准确检测环境中的烟雾、天然气火灾当前煤气值、CO值和有害气体值，并及时控制外设进行处理，使得这些参数处于正常的范围之内，此外，此次设计还增加了远程监测和控制系统，用户可以远程接收监测的设计和远程对其进行控制；此次设计可以解决当前用户由于不及时了解当前环境中的空气参数进行实时监测，导致人们的生命安全和财产安全受到损失。

Abstract
At present, the air quality of people’s living environment is getting worse and worse. At present, most users do not have real-time and accurate detection instruments for a large amount of air quality. In order to solve this problem, this design designs an air quality detection system, which is divided into software design and hardware design. Mq-2 smoke detection sensor detects the concentration of smoke in the environment, MQ-5 detects the concentration of natural gas fire gas in the current environment, MQ-7 detects the concentration of CO in the environment, AND MQ-135 detects the concentration of harmful gas in the current environment. OLED will display the detected data, and when the abnormal concentration of gas is detected, it will alarm the sound and light. And control the fan and purifier work, make the air environment in the normal range, Bluetooth monitoring module, the monitoring data will be transmitted to the user’s mobile phone, users can also remote control ventilation or purifier work through the mobile phone, and control mode switch; Software design, this design uses Kil5 as the programming software of this design; Through software and hardware, after debugging, this design can accurately detect smoke, gas fire gas current value in the environment, CO value and harmful gas, and timely control peripherals for processing, make these parameters in the normal range, in addition, this design also increased the remote monitoring and control system, Users can receive and control the monitoring design remotely. The design can solve the current users because they do not timely understand the air parameters in the current environment for real-time monitoring, resulting in the loss of life and property safety.
