Interesting device … I have been thinking for a while about monitoring my sleep, and this at first seems ideal - however the examples seem to all be for a person sitting in front of the unit.
My main question is whether it can actually detect heartbeat and breathing when there are blankets covering the subject ? Also, how well does it work for people who sleep on thier side ?
I am also curious that other presence detectors provide information on motion/movement of the subject - but this unit does not.
