摘要
随之科技水平的提高，人们的生活水平也得到提高，然而在人们的生活环境中存在很多危害人们身体健康的因素，在室内，当前很多家居质量不过关，导致其内部的甲醛含量超标，家居环境中煤气泄漏是十分危险的事情有可能会引起或者甚至危及住户生命。智能家居系统设计煤气检测模块使一旦发现煤气泄漏事件立即报警，通知用户立即采取有效措施来排除危险。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-5检测当前环境中的天然气或者煤气泄漏浓度，MS1100检测环境中的甲醛浓度，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，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
With the improvement of science and technology, people’s living standards have also been improved, but in people’s living environment there are many factors that harm people’s health, in the indoor, the current quality of many homes is not up to standard, leading to its internal formaldehyde content exceeds the standard, gas leakage in the home environment is a very dangerous thing may cause or even endanger the life of the household. Smart home system design of gas detection module once found gas leakage event alarm immediately, inform the user to take effective measures immediately to eliminate the danger. This design in order to solve this problem, design an air quality detection system, the system is divided into software design and hardware design, hardware design includes: MQ-5 detects the concentration of natural gas or gas leakage in the current environment, and MS1100 detects the concentration of formaldehyde in the environment. OLED will display the detected data. When abnormal gas concentration is detected, sound and light alarm will be carried out, and the fan and purifier will be controlled to make the environment in the air within the normal range. The monitoring data is transmitted to the user’s mobile phone, and the user can also remotely control the work of the ventilation or purifier and the switch of the control mode through the mobile phone. This design can solve the problem that the current user does not timely understand the air parameters in the current environment for real-time monitoring, resulting in the loss of people’s life and property safety.
