Overall, carbon monoxide detectors sense CO fast and alert you as soon as they do. But there’s a surprising amount of variety in today’s Carbon Monoxide sensors.
Some simple models plug into outlets or use a battery and alert you with a loud siren, like the one on your smoke detector. These models are cheap and suitable for multiroom buildings that need several units spread throughout.
Many models include sensors for both smoke and carbon monoxide. These are an easy option that you can swap out your existing smoke detectors for. They also reduce the number of sensors on your walls or ceilings.
You can also find smart models that connect with your home security systems or alert you of danger through a mobile app. These models are expensive but can be a wise investment if you want extra safety for kids and pets at home.
