Steinel Presence detector HF

The world's first true presence detector. No unnecessary after-run time, no unnecessary electricity costs. 100 percent reliable detection through precise high-frequency measurement of the environment. The True Presence Detector reliably detects the presence or absence of individuals over an area of 64 m² by sensing physical micro-movements and human vital functions, such as the rise and fall of the chest or shoulders due to breathing. The new standard in building automation. Easily controllable via app using Bluetooth.
