基于STM32的厨房安全检测系统
Intelligent Kitchen Detection System Based on STM32

厨房是每个家庭里最容易发生安全隐患的地方之一。针对这一问题设计了一款以STM32为主控的MCU方案。以MQ-2型号烟雾浓度传感器和DHT11温湿度传感器作为感知层模块，并将ESP8266模块作为整个系统的网络层；另一方面借助第三方平台阿里云旗下的MQTT服务器作为数据的处理和流转中心以及IoTStudio平台来作为整个系统的应用层。各传感器将采集到的数据以模拟/数字信号的方式传输给单片机，单片机将信号处理成人们可以理解的数据表示形式，通过ESP8266模块传输至云平台，云平台收到数据后将其再进一步发送至MQTT服务器，从而手机端便可以实时地观测到厨房的各种信息。
The kitchen is one of the most common places in a household where safety hazards can occur. 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.
