A multimodal breath analyzer is a high-precision health monitoring device that combines multiple sensing technologies and is specifically designed to analyze and assess the respiratory status of the human body. Through the integration of airflow sensing, pressure sensing, temperature and humidity detection, sound analysis and other detection methods, it can monitor the user's breathing rate, depth, airflow pattern and other indicators in real time to help identify potential respiratory diseases (such as asthma, sleep apnea, etc.). In addition, the system can provide personalized health recommendations to help users better manage their respiratory health. It is suitable for a variety of scenarios such as home health monitoring, clinical diagnosis assistance, and athlete training.
