Replacing a mass air flow sensor is fairly straight forward so most of the cost comes from the cost of the part and not the labor.
Blood flow measurements were taken as the human.
Devices equipped with this new sensor will be able to measure blood flow volume in subcutaneous tissue by placing the device in contact with an ear finger or forehead 2 when light is reflected on blood within a blood vessel the frequency of light varies called a frequency or doppler shift according to the blood flow velocity.
