The Netatmo Smart Carbon Monoxide Alarm looks out for your safety day and night. It measures, in real time, the levels of carbon monoxide, which is an invisible, odourless and potentially fatal gas. If your home has any fuel-burning appliances (boiler, fireplace, gas cooker, etc.), the Netatmo Carbon Monoxide Alarm will monitor the carbon monoxide particles emitted by these appliances.

This can alert your family and the emergency services when you’re not at home so you can take action.
