wow. This is incredible for multiple reasons.

I've seen apps that somehow read what looks like an ecg from the h10, so maybe there's further pretty pictures to be made. Not sure why they'd be helpful, but this is certainly cool to look at.

It's amazing how much information this device throws off, and it all usually gets simplified down to Heart Rate only.

Thanks at the very least for a sample project that I can use to mess with some data acquisition in the future.

Hey no worries and thanks. It was a break-through for this project to find the H10 gives accelerometer data as well as heart rate, so that it would be possible to estimate breathing rate, which I haven't seen other apps do

Isn't it possible to estimate breathing rate with any optical heart rate monitor? See https://en.wikipedia.org/wiki/Photoplethysmogram#Monitoring_..., afaik that's how Fitbit, Apple Watch etc do it

[kbre93]

Yes it's common to estimate breathing rate based on the oscillations in the heart rate pattern. But estimating it from the chest expansion is a more direct method

I never knew the H10 used an accelerometer, I wonder if they use it to help remove false reads during intense movements like those found in running.
