The Fibaro Door / Window Sensor is a battery powered, Z-Wave compatible reed sensor. The Fibaro Door / Window Sensor detects the doors, windows, garage gates, roller blinds etc devices opening, through detaching its two elements. Every time two elements of the Sensor detach, the Sensor sends a signal to the Z-Wave network main controller. This may be used in scenes, but also in alarm and monitoring systems. In addition, The Fibaro Door / Window Sensor may be connected to a DS18B20 temperature sensor, and has one additional input.
