  Breathing monitoring is crucial in healthcare for early detection of health
issues, but traditional methods face challenges like invasiveness, privacy
concerns, and limited applicability in daily settings. This paper introduces
light detection and ranging (LiDAR) sensors as a remote, privacy-respecting
alternative for monitoring breathing metrics, including inhalation/exhalation
patterns, respiratory rates, breath depth, and detecting breathlessness. We
highlight LiDARs ability to function across various postures, presenting
empirical evidence of its accuracy and reliability. Our findings position LiDAR
as an innovative solution in breathing monitoring, offering significant
advantages over conventional methods.
