毕业设计说明书（论文）英文摘要TitleMulti parameter detection system for home environment-Software DesignAbstractNowadays,people pursue high-quality indoor environment,such as storage warehouse,vegetable shed,school computer room,etc.These places also have very highrequirements for temperature and humidity environment.Therefore,it is necessary tocarry out environmental detection,rely on node terminal to detect indoor environmentalquality and control.In many control designs,the detection in the home environment isrelatively small,so we need a detection system in our life,which is very simple tooperate,can detect a variety of parameters,and the price is relatively common.Thisdesign is based on the single-chip microcomputer household environment multiparameter detection system.DHT11 sensor is used to detect the temperature andhumidity,MQ-2 sensor is used to detect the release of harmful gases.After A/Dconversion,the data is analyzed and processed by the single-chip microcomputer anddisplayed.When the detected signal exceeds the set value,then an alarm will occur.Key words single chip microcomputer,temperature and humidity,smoke,alarm
