Make your home safer with Fibaro's compact carbon monoxide detector. The Fibaro CO Sensor protects you against a high carbon monoxide content in the house. For example if you have a gas fire that emits too much carbon monoxide or if you leave the gas on of your cooking appliance. The detector warns you with a light signal and also with a sound signal of 85 decibels. You also get a notification on your smartphone app (Android and iOS) when you have connected the alarm and your phone. On this app you will find recent information about the emissions in your home. If you connect the CO Sensor with the Fibaro app, the detector is compatible with other products that work on a Z-Wave platform. The detector works on a CR123A 3.0V battery that is included.
