With the ability to detect minute movements, meter light intensity and detect if the device itself is moved, the striking new Motion Sensor from Fibaro opens up a wealth of intelligent automation options. By reading light levels in a room, Fibaro can adjust your lighting as natural illumination levels change and ensure optimum comfort and energy efficiency. If there's no motion in a room and Fibaro detects that an iron has been left on, the system can switch it off and prevent a fire. The Motion Sensor features an internal accelerometer that can raise the alarm if the device is tampered with. Now with Z-Wave Plus.
