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. Once a biomimetic ...
