Interesting. I'd be interested in a breathing sensor that can work on someone working at a computer.

I’m sure it can be done with a normal camera and enough light, especially with the advancement of AI technologies in recent years. I haven’t had time to experiment, but if you have an iPhone, you can try this app [1] I installed yesterday to study its feasibility.

On the homepage, there is a video [2] explaining more as well, and their paper [3].

Intel Meteor Lake+ platforms can use NPU for WiFi 7 Sensing.

For older Intel wifi radios, there is custom firmware and many research papers: https://dhalperi.github.io/linux-80211n-csitool/
