The microwave radar breathing sensor addresses a specific cognitive quality issue: environmental system interruptions during focused work. Unlike PIR (passive infrared) motion sensors that detect movement and cut systems (lighting, ventilation) when the user is stationary, HIGHKA’s radar sensor detects presence through respiration — a continuous signal even during deep focus. This means lighting does not dim and ventilation does not reduce during focused stationary work, eliminating the system-generated interruptions that break cognitive state and trigger the ISE recovery cycle. The 0.1-second sensor response also ensures immediate system activation on entry, with no delay period in which the occupant experiences the transition.
