Wireless Respiration Sensor/Spirometer with Mouthpiece

I. Working Principle
The principle of lung capacity testing is based on the laws of gas physics and physiology, measuring the maximum volume of air inhaled and exhaled by the human body. This test is a standard assessment for pulmonary function and physical training, and can also be used for disease diagnosis and treatment. The lung capacity test principle is based on Boyle’s Law, which states that gas volume is directly proportional to pressure and inversely proportional to temperature and humidity. During the test, the subject stands or sits, takes a deep breath, exhales as much as possible, and then inhales as much as possible to fill the lungs with gas. The tester uses a spirometer or flow meter to measure the subject’s lung volume and airflow velocity.
