Research On Internet + WiFi Sensor Remote Monitoring Technology For Smart Home

The development of science and technology has made people's lives easier.People's needs for home life are more than just a living material space.What is being pursued now is a smart living environment that is highly comfortable,convenient,and safe.The goal of this study is to develop a smart home remote monitoring system that is based on the Internet environment with high reliability,low cost,low power consumption,high applicability,and easy popularization.To meet the needs of smart home life,a remote monitoring technology is proposed based on the Internet + WiFi sensor and a remote monitoring system is designed and implemented for smart home.Through the comparison and analysis of key technologies used in the smart homes,The hardware platform and software solution of the system are designed by themselves.The entire monitoring system can be divided into two parts:the controller end and the cloud server end.The sensor nodes in the home are arranged to collect data inside the home,and then through simple processing by the microcontroller,data are sent to the router through the serial port to the WiFi module,and then forwarded to the cloud server through the router.The control commands from the cloud server can also be transmitted to the microcontroller through the WiFi module.Bidirectional data communication can be achieved.The system has four sensor units:temperature sensor,humidity sensor,infrared distance sensor,and LED light switch control.Through the design of the four sensor nodes,the three functions of remote environmental monitoring,anti-theft alarm,and intelligent lighting and the application of scene simulation are finally realized.Through the actual experimental tests,the stability of the entire system is good.The innovation of this research is to combine WiFi technology with the cloud server and apply it to remote monitoring of smart home.The entire system adopts a new architecture of the Internet of Things(IoT)with embedded terminals + WiFi +cloud platform + mobile terminals.The home wireless network composed of WiFi technology is now very popular and is one of the important directions for future development.In addition,the application of the cloud platform technology can not only connect the applications of the Internet of Things in different fields,but also realize the unity of the platform and save the hardware resources,while also enabling data sharing.
