True Presence® from STEINEL is the world's first sensor technology that can detect whether a person is in the room beyond any doubt – even if they are completely motionless. It detects the finest micro-movements such as the lifting and lowering of the chest when breathing, thus ensuring absolute precision. This not only optimises energy savings, but also enables smart, demand-oriented automation solutions for lighting, heating and ventilation. Perfect for applications in offices, hotels or care facilities.
