SystemConnected Carbon Monoxide Detectors

Biomimetic CO Detector Operation Biomimetic CO detectors mimic how hemoglobin in biological organisms reacts to CO. Specifically, a biomimetic sensor monitors infrared light that is passed through a disc of synthetic hemoglobin that darkens in the presence of CO. Thus, as CO concentrations increase, the light is obscured, triggering the alarm.

How Do Carbon Monoxide Detectors Work? | Vivint

20190822· Biomimetic sensor: A special gel turns a different color when it comes in contact with carbon monoxide. The shift in color causes the CO alarm to go off. While this might be the most reliable type of alarm, it is more expensive and generally less common for typical household use. It is used most often in hospitals and hotels.

How Carbon Monoxide Detectors Work | HowStuffWorks

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 sensor has changed color, it must be placed in a COfree environment to reset itself.

Carbon monoxide detector Wikipedia

A biomimetic sensor works in a fashion similar to hemoglobin which darkens in the presence of CO proportional to the amount of carbon monoxide in the surrounding environment. It uses cyclodextrins, a chromophore, and a number of metal salts.

20150713· As I understand it the biomimetic sensor is supposed to act the same way as the hemoglobin in the blood which chemically reacts with CO and turns dark. This chemical reaction is only slowly reversible and makes the hemoglobin unable to carry oxygen. That is how CO kills you. https:///wiki/Carbon_monoxide_poisoning

How it Works Carbon Monoxide Detectors

Types of Carbon Monoxide Detectors and how they work There are three types of carbon monoxide detectors: a biomimetic sensor, a metal oxide semiconductor, and an electrochemical sensor. A biomimetic sensor contains a gel that changes color when it absorbs carbon monoxide. When the gel changes color it triggers an alarm to go off.
