A Kidde plug-in carbon monoxide detector. A carbon monoxide detector or CO detector is a device that detects the presence of the carbon monoxide (CO) gas to prevent carbon monoxide poisoning. In the late 1990s, Underwriters Laboratories changed the definition of a single station CO detector with a sound device to carbon monoxide (CO) alarm.
Kidde (/ ˈ k ɪ d ə / [2]) is an American multinational company that manufactures and distributes fire detection and suppression equipment, as well as smoke and CO alarm units. Kidde is one of America's largest manufacturers of smoke alarms [ 3 ] [ 4 ] and fire safety products. [ 5 ]
The key components are an infrared source, a light tube, an interference (wavelength) filter, and an infrared detector. The gas is pumped or diffuses into the light tube, and the electronics measure the absorption of the characteristic wavelength of light. NDIR sensors are most often used for measuring carbon dioxide.

Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location.
NODE+CO 2, a carbon dioxide sensing module, one of six different gas sensors in the OXA sensor family, raised $26,046 on Kickstarter, $1,046 over its goal on December 31, 2013. [17] In June 2014, Variable Inc. launched an online hackathon competition entitled HACKANODE. It appears at this time (9/13/2018) that Node is no longer available.
"Good Morning America" reports Wong later returned to the slopes with a metal detector and found his iPhone - Chris Wong says he lost his iPhone while skiing in Vermont, so he searched the slopes ...
In 1918 Walter Kidde & Company purchased the rights to the "Rich" system for on board fire detection and suppression. The problem with this system was steam was used to put out fire, which then caused considerable damage to the cargo on the ship. Kidde came up with the solution to use carbon dioxide instead of steam.
Colorimetric capnography is a qualitative measurement method that detects the presence of carbon dioxide (CO2, a relatively acidic gas) in a given gaseous environment. From a medical perspective, the method is usually applied by exposing litmus paper/film to an environment containing a patient's airway gases (i.e. placing it into their breathing circuit/airway circuit), where it will then ...
