FIBARO CO Sensor is an ultra-light, compact, battery-powered carbon monoxide detector, designed to be placed on a wall.
Its high sensitivity allows detecting the presence of the carbon monoxide (CO) gas at the early stage to prevent carbon
monoxide poisoning. The alarm is signaled with a built-in siren, blinking LED indicator and by sending commands to Z-Wave network devices.
Additionally, the device is equipped with a temperature sensor.
