| Summary: | 碩士 === 輔仁大學 === 資訊工程學系碩士班 === 105 === People are often exposed to the danger environment of subtle and harmful pollution due to their job. They rely on the protection of face mask to avoid being harmed by the contaminant. However, incorrect wearing or aging of face mask may produce interstices between the face mask and human face. It may cause harm to the health of the face mask users. How to provide a real-time warning message for the face mask users is an important issue. The work proposes an intelligent tightness detection system of face mask for detecting the interstice problem. The system uses CO2 sensor, sound sensor, Arduino and Bluetooth devices to dectect the CO2 concentration and sound of breathing and send the data to the mobile device. Experimental results show that the system can correct, persistent, and real-time to detect the face mask tightness of the users and also effectively enhance the protection effect of the face mask.
