Abstract
This graduation thesis presents the design of a microcontroller-based disinfection device, utilizing the STM32F103C8T6 microcontroller as the main control chip. The disinfection device is equipped with the following functionalities: liquid level detection and alarm, human body temperature detection and alarm, disinfectant spray and drying, temperature threshold setting, and data display with remote monitoring.The liquid level detection and alarm feature utilizes a liquid level sensor to monitor the level of the disinfectant. When the liquid level falls below a certain threshold, a GSM module is employed to send an alert SMS, notifying the user to replace the disinfectant.For human body temperature detection and alarm, a non-contact infrared temperature module and an infrared obstacle avoidance tube are employed. When the measured temperature exceeds the preset upper or lower limit, the system locks the temperature for a specific duration. Simultaneously, an audio-visual alarm is triggered, and the GSM module sends the temperature value and alert information.The disinfectant spray and drying process involve three infrared obstacle avoidance tubes to select the spray intensity (high, medium, or low). The MX1508 and PWM are utilized to control the atomization plate, enabling efficient disinfectant spraying. After spraying, a predetermined drying time is initiated, where relays control the fan and heating element.Users can set upper and lower temperature limits via a button interface, enabling customization of the temperature threshold.
To facilitate data visualization and remote monitoring, an OLED display is employed to show real-time measurements, including the liquid level status and human body temperature. Additionally, a WIFI module enables users to access real-time liquid level status and temperature measurements remotely via a mobile application, while also allowing for temperature threshold adjustments.
The design incorporates various sensors and modules to achieve intelligent control and monitoring of the disinfection device. By enabling remote monitoring and customization, users can conveniently access and control the operational status of the disinfection device, thereby enhancing safety and usability. The proposed design exhibits practicality and potential for widespread application in various settings that require effective disinfection.
