Which device is designed to detect carbon monoxide levels in a home?

The device designed specifically to detect carbon monoxide levels in a home is the carbon monoxide alarm. This type of alarm is engineered to sense the presence of carbon monoxide, a colorless, odorless gas that can be harmful or even fatal at high levels. When the carbon monoxide alarm detects this gas, it emits a sound to alert occupants of its presence, allowing them to take action to ensure their safety.

Smoke detectors, heat detectors, and flame detectors serve different purposes. Smoke detectors primarily monitor for smoke particles generated by fires, while heat detectors respond to changes in temperature rather than the presence of gases. Flame detectors are used to identify the specific presence of flames, often in commercial or industrial settings. Each of these devices plays an important role in fire safety but does not provide the specific detection that carbon monoxide alarms are designed for.
