LifeSmart Human Presence Sensor
24 GHz presence sensing — detects breathing, not just movement
LifeSmart products are specified and installed by DBGTECH as part of a project. Tell us about your space and we'll quote the right system.
Overview
A PIR sensor sees movement, so lights go out on someone sitting still. This one uses 24 GHz microwave sensing and detects breathing, which means it knows the difference between an empty room and a quiet one — the single most common complaint about occupancy lighting.
Mounted in a 55 mm ceiling cut-out at 2.5–4 m, it reads large movement at 3–4 m, minor movement at 2.5–3.5 m and breathing at 2.5–3.5 m (measured at 3 m height). Sensitivity sets in 10% steps and the off-delay runs from 30 seconds to 30 minutes, both from the app. A built-in illuminance sensor lets a rule hold the lights off when there is enough daylight.
