Let’s take a deep dive into what good CO detectors do and how they work, so you can keep one ugly, invisible killer out of ...

Carbon monoxide detectors continually monitor the carbon monoxide levels in your home and alert you if they reach unsafe levels. ... There are three types of carbon monoxide sensors: metal oxide, ...

Carbon Monoxide is often called a silent killer because of its invisible, odorless nature. That makes installing a Carbon Monoxide detector even more critical. Here are CNET's top picks.

Metal oxide semiconductor; the alarm is set off when the circuitry of the silica chip detects carbon monoxide. This causes the electrical resistance to drop, which in turn causes the alarm to sound.

CO detectors measure the concentration of carbon monoxide in the air, triggering an alarm if it's high enough. There are ...

There are several different ways to detect carbon monoxide, but most home carbon monoxide detectors use an electrochemical sensor. These rely on how the behavior of a chemical changes when carbon ...
