The Aqara Presence Sensor FP2 uses state-of-the-art millimetre wave radar technology that can accurately detect the presence of people, even with slight movements. This technology ensures the continuity and stability of the smart device. It can also control other smart home devices through ecosystems such as Apple Home to achieve wider applications. It has features such as human fall detection and a built-in light sensor. Zone positioning: It offers significant advantages over traditional PIR infrared motion detectors as a single radar sensor can be used to monitor rooms of up to approximately 40 m². Furthermore, you can divide the room into up to 30 zones, e.g. sofa, bed or desk. In addition, you can set up individual automation for each zone. It's like using several PIR motion sensors at the same time with one presence sensor, FP2. Multi-person detection: Up to 5 target persons can be detected at the same time. The result is that the system not only divides the room, but also automatically reacts to the position of the different people without interfering with each other. Ultra-high precision: privacy and detection accuracy are taken into account. It is able to detect non-inductive signal detection without collecting real images. Automation can generally be done locally. Millimetre wave radar technology is more stable than detection by infrared sensors, even when you are sitting or sleeping.
