ABSTRACT
With the improvement of people’s living standards, the comfort and safety of kitchen environments are increasingly being focused on. Traditional range hoods have limited functions and can hardly meet the modern kitchen’s demands for environmental monitoring and intelligent control. The safety hazards such as high temperatures, cooking fumes, and combustible gas leaks generated during kitchen cooking urgently need a range hood system that can monitor and control in real-time to ensure safety.
The STC89C52 microcontroller-based intelligent range hood has been developed to address these needs. It integrates a variety of sensors and functional modules to monitor key parameters in the kitchen, such as temperature and combustible gas concentration in real-time. It also features smart lighting control through human body infrared detection and photoresistors. When abnormal conditions are detected, the system can automatically activate the corresponding functions and trigger alarms. It also supports threshold setting via buttons and manual control. Combined with the LCD1602 display, it can intuitively present data, providing strong protection for the safety and comfort of the kitchen environment. This system is an essential smart device for modern kitchens.
The intelligent range hood system has many advantages. It can monitor the kitchen environment in real-time and intelligently control functions such as fire extinguishing, ventilation, and lighting based on preset thresholds to ensure the safety and comfort of the kitchen comprehensively. It integrates various high-precision sensors that accurately capture changes in the kitchen environment and provide reliable data for intelligent control. When an abnormality occurs, both sound and light alarms and SMS reminders are triggered to ensure that users are informed and can take action in time. The LCD1602 display intuitively shows data and status, and the button operation is simple, making it convenient for users to set and control. With the help of the WIFI module and mobile app interconnection, users can remotely view data, set parameters, and receive alarms, realizing intelligent remote monitoring. It has a broad application prospect in places such as home kitchens, catering industry, and hotel kitchens, promoting the intelligent development of kitchen equipment and bringing significant social and economic benefits.
