Presence detector True Presence® - Steinel

The world's first true presence detector! No unnecessary stay-On times any more – no unnecessary electricity costs. Precision high-frequency measurement of the surrounding area provides 100% reliable detection. The True Presence® detector reliably identifies whether persons are present or absent over an area of 64 m² – on the basis of the body's micro movements as well as human vital functions, such as breathing in and out, or shoulder movement. The new standard in building automation.

Looking forward follows looking up. True Presence® was developed to be the first true presence detector. It reliably indicates if a person is in the room or not. This means that reliable absence detection is possible for the first time. This information allows the reliable activation and deactivation of lighting without the need for stay-On times and without any waste of electricity. The detailed knowledge concerning presence and absence results in numerous other applications that can be very valuable for building management.

This sets a new standard in advanced building automation.
