Abstract |
|
Spirometer measures the amount of volume and flow rate of air that is inhaled & exhaled. Spirometer is a noninvasive diagnostic instrument. This paper represents the comparison of three different spirometer sensor designs. 1st design of spirometer sensor is made up with using Infra-Red Transmitter – Receiver. 2nd design is made up by using LED (Light Emitting Diode) – LDR (Light dependent resistor) pair as visible light Transmitter – Receiver. 3rd design uses differential pressure sensor which senses difference in air flow pressure. |
