Aqara's FP2 Presence Sensor uses state-of-the-art millimetre wave radar technology that can accurately detect the presence of people even when there is little movement. It also has a zone positioning feature that allows different conditions in different zones, such as beds and tables, to be automated. A room can now be divided up to 30 small zones and detect up to five targets (multi-person detection).
