Design Of Home Environment Monitoring System Based On WeChat Platform

With the rapid development of science and technology as well as the improvement of people's living standard,smart home came to be known,and remote monitoring function is an important part of smart home technology.People can control the air conditioners,humidifiers,air purifiers and other electrical appliances in their homes to create a comfortable environment before they get off work.The design idea of traditional smart home is to take PC page or mobile phone APP as the platform for users to view and control,and realize the acquisition of environmental information and the control of electrical equipment through a terminal device that can realize network access.The disadvantage of PC terminal is poor real-time data acquisition,low convenience,long APP development process and high research and development cost.At the same time,different terminal systems must be taken into account.WeChat is one of the popular social tool nowadays,and its function is not only limited to social interaction,but also brings people convenience in online payment,cultural communication,shopping and other aspects.In view of the deficiencies of the current home environment monitoring system,this paper aims to study and design a home environment monitoring system that can realize remote monitoring through WeChat platform.This design takes STM32F103 as the main controller,using ZigBee wireless network transmission technology as the communication mode of the system equipment,and completes the circuit design of each functional sub-module,including temperature and humidity detection,dust detection and relay nodes.Through the current widely used social networking tools WeChat platform to obtain the data acquisition of temperature,humidity,concentration of combustible gas and smoke dust concentration,in the meantime,remote control of the air conditioner,air purifier and other home appliances are also realized.The alarm information will be automatically sent to the user through the WeChat platform when the concentration of combustible gas in the room is detected to exceed the standard.In addition,through the Ethernet module we can realize the network access system,WeChat platform,the user terminal access,acquire environmental data and send control command.The SAE cloud platform is a medium of WeChat platform and the main controller to realize remote control of household environment monitoring and equipment,which can be opened by WeChat platform automatically to adjust the switch,the system based on the current environment parameters can automatically open the related equipment to bring people a comfortable and convenient life.This system realizes remote monitoring through WeChat,which shortens the development time on the premise of ensuring the effect.This system can effectively make up for the shortcomings of the current intelligent home system,and achieve remote monitoring of the home environment through the WeChat platform.The system also has the advantages of low cost,low power consumption and easy expansion,and has certain application value.
