This paper aims to design and implement an intelligent kitchen safety monitoring system based on the STM32F103C8T6 microcontroller. The system integrates MQ-5 and MQ-2 gas sensors, an electromagnetic valve (simulating a stepper motor), a sound and light alarm, a ventilation device, an OLED display, and a WIFI module. By using the MQ-5 gas sensor, the system detects the concentration of combustible gas. If the concentration exceeds the set maximum value, the system automatically closes the electromagnetic valve, triggers the sound and light alarm, activates the ventilation device, and sends an alert message to the user’s mobile phone. Additionally, the system utilizes the MQ-2 sensor to detect smoke concentration. In case of a fire, the system activates the sound and light alarm and sends a fire alarm message to the user’s mobile phone. The monitoring data is displayed on the OLED screen, and users can set various thresholds through buttons. Moreover, the WIFI module enables users to remotely access real-time monitoring data on their mobile phones and control the system remotely, including setting thresholds, switching the electromagnetic valve and fan, and other functions. This paper designs and implements an intelligent kitchen safety monitoring system, which enhances kitchen safety, effectively prevents combustible gas leaks and fire incidents, and provides users with a convenient monitoring and control approach.
