Really Homemade Oximeter Sensor - Arduino Project Hub

May 13, 2020· Building the oximeter (hacking the KY-039 sensor) to find oxygen saturation Our blood absorbs light in a different way with the change of the wave-length of the light. The red light ( ~600nm ) is absorbed better by the blood that contains more oxygen, so we can compare the measures made with infrared led ( ~950nm ) with the ones made with red ...
