The FIBARO Motion Sensor is a small, wireless motion sensor shaped like a cat's eye that can be used to monitor activity in the home. It has a wide field of view and long range, allowing it to detect motion even from far away. In addition to motion detection, it can also measure temperature, light levels, vibrations, and other factors. The sensor is powered by a long-lasting battery and connects to the home's central controller via Z-Wave to automate functions and provide alerts to homeowners. It is designed to help users feel safer and more comfortable in their home.
