A carbon monoxide detector is a safety device that detects the presence of carbon monoxide gas in the air. Carbon monoxide is a colorless, odorless gas that can be harmful or even deadly if inhaled in large amounts. The detector senses the gas and triggers an alarm to alert people in the area. These detectors are commonly installed in homes near sleeping areas or heating sources, such as gas appliances or fireplaces. Regular maintenance and testing are important to ensure the detector works properly, providing an early warning and preventing carbon monoxide poisoning.
