Jiminex is categorically wrong.  The detector doesn't *see* air temperature.  When warm (or cool) air moves across in front of the
detector without touching it and without heating or moving a visible object, the detector is unaffected.  Jiminex is confused by the
difference between air movement in view of the detector and air *striking* the detector.  The latter can easily trip many PIR
detectors.  That is one of the reasons it is important to seal the wire entry hole in a PIR.  But it is not a problem unless the air
current hits an object within the detector's field of view or the detector itself.
