Hello,
Would it be possible to exclusively emit green light? It seems like the only option to emit green light is to do it in combination with Red and IR light, but it would be great if I could minimize noise and only emit green light.
I have been measuring readings (PPG) using green light and also noticed that the sensors are rather sensitive to the pressure being applied. Would readings be better if I were to take readings with my finger close to but not touch the sensors? I know that modern pulse oximeters typically have a thin glass surface separating the two.
