To whom it may concern

I'm trying to monitor SPO2 values returned by e-Health platform ver 2 from serial monitor in Arduino IDE.
The board is Arduino UNO.

But, the values are completely different.

For example, when the pulse oxymeter display reads "98", serial monitor shows "6" or "0"
consecutively.

I found similar topic posted by TFK in this forum.
In that topic, the team recommended dompiling the sketch using older version of Arduino IDE (Arduino 1.0.1)

I tried this solution but to no avail.

I also have the following problems.
1. I cannot read ECG-like ECG from ECG sensor of yours.
2. the temperature values returned by e-Health sensor is about 3 degrees higher.
3. EMG sensor picks up only noise.(No phasic response observed when flexing muscle)

But probably, you demand me to post these as separate tipocs.

So, for now, I wait for your response abot SPO2 problem.

Hello hhhddd,

We can recommend that you use all versions of the library to identify if it works well with any of them:

You mean...I should try all five versions of libraries?

I'm using the latest version.

Is it possible that some older library is better at handling pulse oxymeter data?

Isn't there any suggestions about which version is most suitable?

Hello hhhddd,

yes please try every library version, since there are different types of SPO2 and each type works with a different version of the library.

Thank you for your suggestion.

I have two questions.

First, as you can see in other topics i posted, I'm experiencing many problems in your product (and they are driving me mad )

Do you think that using different version of library solves problems in sensors other than SPO2?

Second, I've already tried two different versions the day before yesterday (I did not take note of which version of library I tested), because your stuffs made same suggestions for SPO2 problem similar to mine in topics a few years ago.

But, at that occasion, compiling of arduino sketch failed. (again, i took no record of error message)
Do you have some ideas about the cause of this failure?

best regards

Hello hhhddd,

testing the different versions of the library, in effect, can solve your problem with the SPO2 sensor since there are different versions of this sensor that have been sold over time, and each version requires a different library.

Hi everyonne

sorry for bothering you, but i gave up.

Hello hhhddd,
