ABSTRACT

With improved living standards, people pay more attention to health and safety, and household disinfection cabinets have become increasingly important in modern families. In the past, the disinfection cabinet mainly relied on simple mechanical switches; the operation was not flexible enough, and the disinfection effect was difficult to guarantee. Therefore, the traditional disinfection cabinet could not meet the needs of modern families. The system comprises a temperature and humidity monitoring module, LCD interface, physical key input, stepper motor driver, sound and light alarm system, relay, and Bluetooth wireless communication module. An intelligent disinfection cabinet with comprehensive functions and convenient operation was completed. By accurately controlling the temperature and humidity of the disinfection cabinet, the system can ensure the effectiveness of the disinfection process. The system can give the user feedback on the working state of the disinfection cabinet in real time with the LCD. Users can remotely control the disinfection mode, disinfection time, and system switch of the disinfection cabinet by independent buttons or a Bluetooth mobile phone app paired with the system, which significantly improves its convenience. In addition, the system is equipped with a temperature monitoring and protection mechanism. When the detected temperature exceeds the set threshold, the system will immediately trigger the sound and light alarm and send reminders to the user through the mobile phone app to ensure the safety of the use process.
