Inspired by the beliefs of the ancient Egyptians, Fibaro has designed the world's smallest, wireless motion sensor shaped it like a cat's eye. The Fibaro motion sensor combines four useful functions into a tiny, wireless Z-Wave motion sensor! It functions as a motion sensor, temperature sensor, light sensor and a vibration (accelerometer) sensor, thanks to its built-in accelerometer. The multicolor LED Pupil of the Fibaro motion sensor informs family members if it has detected any motion or the current temperature of a room. Set the color and its intensity to your liking and, as soon as you enter a room; you will know immediately what the temperature is. It can also trigger pre-set scenes such as lights turning on when you walk in the room. Please note that some of the advanced features of this device may require the Fibaro home center 2 (HC2) or HC lite controller. Our motion sensor is compatible with most Z-Wave controllers such as HC2, HC lite, Vera, Nexia, urc, Clare controls and home seer.
