Design Of Home Environment Monitoring System Based On Internet Of Things

With the rapid development of urbanization and the improvement of life quality,more and more people pay attention to the home environment.The bad living environment will induce various diseases,such as respiratory diseases,leukemia.The water and gas will affect the safety of home life.Therefore,the research of home enviroment monitoring system is of great value and significance to meet the requirement of high quality and safe indoor environment for people.It is very important.Considering the problems of the indoor environment,this paper studies the home environment monitoring system based on the Internet of things.This system has a number of indoor health environment parameters monitoring function.It can also detect household gas and water flow.So it is different from the other indoor air quality monitoring system.This system which is based on the internet of things has the remote view and remote alarm function for users.This system acessing to networking is more integrated,networked and remote,and can fully protect the home life safety,comfort and health.In this paper,according to the internal air quality standard of GB/T18883-2002,the overall structure is designed based on the basic idea of comfortable home,healthy home and safe home.The hardware circuit is designed on the basis of framework.And this paper introduces a overall indoor environment comfort evaluation method.The design of methane,water temperature,humidity,air pressure,dust,formaldehyde and other parameters monitoring is completed.Taking STM32F103RCT6 micro processing as the core,the sensor signal acquisition circuit,power supply circuit,liquid crystal display circuit,wireless data transmission circuit are designed.And based on the C language,the program and debugging of the control and data acquisition,data correction,data packing and wireless data transmission are completed.The experimental results show that the home environment monitoring system based on the internet of things can achieve its function and basically meet the requirement of index.
