Breath measurement sensor based on detection of carbon dioxide

Abstract

A non-invasive breath sensor that allows a continuous measurement of person's breathing, while they are making a physical effort is the target of this work. This work achieved the design, implementation and evaluation of a sensor for breathing measurement. After testing the sensor, we observed that it has a response in the presence of the CO2. This response was proportional to the quantity of the CO2 that was injected to the sensor. The acquisition data array was good for a testing process.
