First off, let me declare my variables.
- I’m terribly new.
- I want to learn.
- Not even sure this is even valid.
- Sorry if this is in the wrong section.
Background: I want to buy a cheap pulse oximeter (http://www.amazon.com/Finger-Pulse-Oximeter-SM-110-Carry-Wrist/dp/B003TJH3LI). Notice there is no functionality to record trends in o2 sat/ HR.
Goal: I would like to, if possible, attach an analog input into the existing circuit to be able to graph/write/whatever. record the changes over time.
- Is this feasible?
(I know i haven’t purchased the meter yet, and don’t have the circuit)
- Is there anything in general that I would try to identify to connect to the right location?
