Gas sensors

— fire detectors that react to the presence of a certain gas in the air.

The specific format of operation of such devices may be different. So, some models react to carbon monoxide (CO) – not only is it a product of combustion and a sign of fire, but it is also dangerous in itself, so such a sensor also provides protection from carbon monoxide poisoning. A number of devices are triggered when a significant amount of household gas appears in the air (for example, from an open burner or a damaged pipeline), methane, propane-butane, etc. – in such cases, timely notification helps to avoid an explosion. Finally, sensors that are able to detect sleeping gases are marked separately.

Note that gas sensors may also have smoke and/or temperature response functions.
