How Carbon Monoxide Detectors Work | HowStuffWorks

­CO detectors can use several types of sensors to sense carbon monoxide in the air. Biomimetic sensor technology reproduces CO's effects on hemoglobin in the blood. In a biomimetic sensor, a gel changes color as it absorbs CO. A separate sensor detects the c­olor change and alerts the detector's processor to sound the alarm.

How to Determine If Carbon Monoxide Detectors Work | Hunker

Jun 07, 2021· Many kinds of CO detectors use replaceable batteries. (If you have a 10-year sealed carbon monoxide detector that uses a lithium-ion battery, there's no replaceable battery. Instead, you'll need to buy a new unit when the battery dies.) Even if you use plug-in carbon monoxide detectors that only use batteries as backup, keeping batteries fresh is essential because a CO leak could happen …
