Abstract:Abstract: Air conditioning consumes a lot of electricity, improper management will waste a lot of electricity, research and implementation of air conditioning intelligent control system is imperative. This paper designs an intelligent air conditioning control system based on Internet of Things cloud platform. The whole system is divided into three parts: mobile APP client, intelligent cloud platform and intelligent air conditioning control terminal based on STM32. The smart air conditioner control terminal module collects temperature and humidity data of the surrounding environment in real time, processes the data through STM32 microcontroller, and then sends the data to the mobile phone terminal through ESP8266WIFI module. Users can also change the relevant Settings on the mobile phone APP terminal, and then the mobile phone terminal sends the data to the cloud platform. Finally, the cloud platform sends it to THE ESP8266WIFI module through WIFI network to realize the function of remote control of air conditioning. The experimental results show that the system can monitor the ambient temperature and humidity data in real time, effectively control the reasonable use of air conditioning, control success rate of 100%, can create a comfortable living and working environment without waste, suitable for a variety of air conditioning brands, has high practical value.
