To address this issue, a solution has been designed based on an MCU scheme with STM32 as the main controller, MQ-2 smoke sensor and DHT11 temperature and humidity sensor as the data acquisition module, ESP8266 module as the communication module of the whole system;On the other hand, the MQTTT server under the third-party platform AliCloud is used as the data processing and flow center and the IoTStudio platform to develop and design the mobile terminal visual interface. Each sensor transmits the collected data to the MCU in the form of analog/digital signals, and the MCU processes the signal into a data representation that people can understand, and transmits it to the cloud platform through the ESP8266 module. After receiving the data, the cloud platform further sends it to the MQTT platform. Thus, the mobile phone can observe all kinds of information about the kitchen in real time.展开更多
