Internet technology has become a major player in the process of urban intelligence, playing a pivotal role. Along with many new-generation information technologies with universal value embedded in the corner of the city, a large number of applications have realized the high integration of smart technology, the high-end development of smart industry, the efficient and convenient service of the smart, and the leap from digital city to smart city. Among them, the application of remote temperature control in the smart home greatly enhances the convenience of the user's life: the temperature controller can obtain the indoor environment information in real time through the network, and adjust it in real time, which is convenient and quick. The following figure is an illustration of the intelligent thermostat scheme based on WIFI network:


Introduction of intelligent thermostat based on WIFI network:
Integrated WIFI module can be remotely controlled via mobile app or webpage.
Integrated air quality sensor to detect indoor CO2 and volatile organic compounds, thus controlling the fresh air system and air quality purifier to create a good living environment.
Integrated infrared sensing, it is more convenient to wake up the system when people are close; In the out mode, the intrusion alarm function can be implemented.
Integrated humidity sensor detects indoor humidity and controls humidification and dehumidification equipment to achieve a comfortable living environment.
Intelligent learning user preferences, adaptive adjustment of room temperature, more humane.
Provide a powerful cloud computing platform that automatically adjusts the temperature control mode based on local climate change.
Through the data stored in the cloud, you can see the recent working curve of the thermostat; Through the analysis of big data, it can provide users with more applicable energy-saving solutions.
The open wireless interface can be connected to different smart home platforms to remotely control lighting, curtains, home appliances, security and more.
