In today’s world of smart automation, the demand for advanced sensing technology is rising. Traditional presence sensors have been widely used for lighting control, security, and energy management. However, they often rely on simple motion detection, which can lead to inefficiencies. This is where true presence sensors come into play. Unlike conventional motion sensors, real presence sensors detect actual human presence, even when the person is stationary. With innovative technologies like the Crux Detector, Pulse Detector, and Master Pro, presence detection is evolving into a more accurate and reliable solution.
