what are the distance of the sensors to the finger.
Quotewhat are the distance of the sensors to the finger.They are normally in contact with the finger. The idea is that the IR bounces off the bone so they are angled slightly towards each other.However, this sort of sensor requires you to be quite still while you take the readings.This is a diagram of something I made back in April 1984
Is it possible to use a nellcor max-a disposable pulse oxi into a arduino.
I am having difficulties in detecting a pulse using the arduino.
When the two sensors across.
Must the monitoring led turned off?
Sorry, I attached two pictures only one made it, so here is the other one.QuoteIs it possible to use a nellcor max-a disposable pulse oxi into a arduino.I would imagine so yes.QuoteI am having difficulties in detecting a pulse using the arduino.What amplifier are you using, it is a very small signal and it needs amplifying.QuoteWhen the two sensors across.There is only one sensor, the two outputs from that sensor are shown in that diagram as SK and SA.QuoteMust the monitoring led turned off?No there is no reason to turn off the LED. Note that this is an IR LED, they work better getting through the skin.

My adviser just give me this pdf as reference
Wow.. lord knows I would be pissed off finding this link. That's Simon's book, right? And people get twitchy when I get twitchy about copyrights. I don't know what he does for a living, I certainly hope that he doesn't make a substantial income from that book..And this is why authors, musicians, and graphic artists are now SCREWED.
