Hi, I'm trying to decide which sensor I should buy for my project, which would involve extracting heart rate from the respiration signal (e.g. see this MIT Vital-Radio paper witrack.csail.mit.edu/vitalradio/content/vitalradio-paper.pdf). What I would like to know is if you think the respiration signal from the X4M200 is precise enough to extract the heart rate from it (as in the paper mentioned above, see attached screenshot) or if i would need to have access to the raw data. Further, if I do indeed need access to the raw data, is the X4M03 better suited for that task? Also, by buying the X4M03 development kit (https://www.xethru.com/shop/x4m03-development-kit.html), am I ready to go or do I need to buy additional sensors/pieces to get working? Thank you for your time, Leoluca.
