What Is a Carbon Monoxide Detector?
A carbon monoxide detector is a device that senses carbon monoxide gas in the air and sounds an alarm when it detects a dangerous buildup. Carbon monoxide is a gas that has no color or smell. Fuel-burning equipment can produce the gas during operation.

- A smoke alarm doesn't always detect carbon monoxide.
How Carbon Monoxide Detector Works
A carbon monoxide detector uses a sensor to check the surrounding air. In a common sensor design, carbon monoxide reacts with a material inside the device. That reaction creates an electrical signal that the detector interprets.

The detector evaluates the signal and sounds an alarm when its sensing system calls for a warning. Its response depends on the gas level and how long the sensor detects it. The sound alerts people nearby, even though the gas itself isn't visible.
A detector needs power to operate its sensor and alarm. Some models use a battery, while others connect to household wiring. A wired model may also have a backup battery. The power arrangement depends on the product.
From the Chris Miller Electric team
When we install a carbon monoxide detector, we check the product's mounting and power instructions. Our team also looks at the wiring route for a hardwired model. The location and power source shape the installation work.
