Comment on Humans can be tracked with unique 'fingerprint' based on how their bodies block Wi-Fi signals
unmagical@lemmy.ml 1 week agoIf all you need is presence detection then a motion sensor would be vastly more efficient.
If you actually need identity detection, then maybe, but you’ll still have to have a camera or detailed access logs to associate the interference signature with a known entity and at that point you may as well just put an RFID reader under the bowl you throw your keys into or use facial or gait detection.

A motion detector is far more inferior to precense detectors, most just use milimator wave though.
