- amelius 9y agoPerhaps a tiny fraction, and that's detected (?)
- simias 9y agoI'm not entirely sure about it but I guess they used "human exhalation" as a somewhat relatable unit of volume for a gas but the actual system has nothing to do with detecting humans? That's the only way that makes sense to me, although if that's the case that's really needlessly confusing.
