| In today's society,the development of science and technology presents the situation of blowout.The constant proposal of new theories and the real-time application of new technologies bring about the rapid changes in people's lives.In these new technologies and applications,Internet of things,cloud platform,5g and other terms have been mentioned one after another,among which smart home is a comprehensive technology field.Compared with the traditional home,smart home is favored by manufacturers and the masses because of its advantages of remote control,real-time monitoring,accident alarm and so on.Domestic and foreign manufacturers have launched their own set of smart home.Due to the fierce market competition,the matching price of smart home is also constantly reduced,giving consumers a lot of choices.However,due to many manufacturers,complex product types,product incompatibility and use difficulties,the development of smart home is still in the Red Sea period.By analyzing the development of smart home at home and abroad and various existing technologies,this paper designs a cloud platform smart home control system based on Arduino,which can monitor and set the state of home environment(LED light,indoor temperature and humidity,smoke concentration,human body induction,etc.),as well as necessary operation feedback,and collect The data is processed by further filtering algorithm,so as to improve the accuracy of the system data.There are three advantages of the system:first,Arduino is used as the main control board and development platform to simplify the development of hardware;second,smart home development is carried out by using Gizwits platform,unified planning and development steps to accelerate and simplify the ecological integration of smart home;third,ADC filtering algorithm is used to process the collected data to ensure the accuracy of the data.The thesis is divided into three parts.One is the device part:Arduino Uno R3 is the main control chip,equipped with temperature and humidity sensor to measure the temperature and humidity in real time,equipped with smoke,flame,human body infrared sensor to detect whether the indoor environment has changed,and through the configuration of buzzer for alarm feedback,equipped with LED lights for remote switch lights,plus NodeMCU as WIFI module to realize the network access with cloud devices,data connection,command distribution.The second is the cloud part:product creation,data point design and code writing are carried out on the smart cloud.In this part,ADC filtering algorithm based on arithmetic average is used to accurately measure the data.The third is the mobile terminal part:develop the mobile APP in the Android development environment.Finally,the reliability and functionality of the system are verified by the virtual device test and the real device test in the cloud.It provides a certain reference value for the future development of smart home. |
