How does a Carbon Monoxide Detector Work?

It took nearly a quarter of a century after smoke detectors came on the scene in our houses, but in 1993 carbon monoxide detectors were finally available to residential homes to work alongside their smoke detector counterparts. Both are of absolute importance to our family’s safety in our home.

Unlike the appearance of smoke and fire in our homes, carbon monoxide is invisible. This gas can sicken, and even kill, those exposed to it over a period of time. It is produced by the fuels in our home that may not be burning completely and producing this unseen poison.

3 Types of Detectors

Biomimetic sensor: This type works similar to the way CO reacts to our body. A gel is used that will absorb the carbon monoside, similar to the way our blood absorbs CO2. This color change then triggers the alarm.

Metal oxide semiconductor: This type uses an integrated silica chip. When it comes into contact with CO it lowers the electrical resistance. That change is detected and sounds the alarm.

Electrochemical sensor: This type is similar to the metal oxide semiconductor, but instead of a silica chip, it uses electrodes in a chemical solution. This type is often used in professional equipment that can detect dangerous amounts of CO instantly.

Every home should have this early warning system. Douthit Electrical can discuss with you the many types available, as well as the locations for installation to best protect your home.
