Hi, I'm trying to understand if the X4M200 Respiration Sensor is suitable for my application, and after reviewing the data sheet and demo videos, I'm still not sure if it is suitable. 1. I need to give real-time visual feedback on the user's breath, so the latency of the respiration pattern output from the module is important. The only spec on latency I can find is that the output of the respiration pattern is in "real time". However, this video demo shows the respiration pattern significantly out of sync with the person's breath: XeThru X4M200 Respiration Sensor Demonstration This demo of the previous version of the module shows respiration pattern is more in sync with the breath XeThru Respiration Monitoring Demo Is the respiration pattern output actually real time without significant delays that would be obvious to someone comparing their own breath and the respiration pattern output? 2. Ideally I want my users to be standing to interact with my device, not sitting, and definitely not lying down. As I understand, the sensor is just measuring distance to the closest person, and detecting the slight changes in distance when the person's body moves due to breathing. If the user is standing, they will be swaying slightly, which I assume would interfere with the correlation of the respiration pattern output to their actual breathing, and could interfere with the RPM count. As I don't yet have a sensor here to test myself, could someone tell me if slight movements while standing are likely to significantly reduce the quality of the respiration pattern output? Is the RPM count likely to stay accurate even if there are slight movements from standing while the sensor is counting respirations?
