There is a screen placed in the center of transparent part in the front of Respiration Sensor. The blow-in air will form pressure difference behind the screen. The tubes in front of and behind the screen transfer it to pressure sensor. Stronger the air flow passes through screen, bigger pressure difference will be formed. Sensor can transfer the pressure value into velocity of air flow. The air flow velocity will be transfer to volume by the formula designed in software.
