pulse oximetry wavelengths
Hey all. I need to build a pulse oximeter for my final project in college but i still have one doubt about the wavelengths
do these waves need necessarily to be 660nm for the red led and 910nm for the IR led?
I have a 875nm wavelength IR led here. Will it be ok?
Thanks for the help
Aw. And what about the photodiode? Or should I use a phototransistor instead? What is better?
thanks again
