The carbon dioxide gas sensor measures gaseous carbon dioxide levels by detecting the quantity of IR radiation absorbed by carbon dioxide molecules. The sensor employs a hot metal filament that acts as an IR source to generate IR radiation. The IR source is located at one end of a sensor tube, and another end is provided with an IR sensor.
How Carbon Monoxide (CO) Detectors Work. CO detectors measure CO levels in the environment and sound an alarm to warn you to ventilate the affected area. Two basic types of CO detectors. CO detectors are either battery operated or electric. Most CO detectors on the market use one of the following three sensor types. 1. Electrolytic Sensor Detectors - This type of sensor is extremely sensitive to detecting CO in the home.
