The global gas sensor market is segmented by gas type, technology, and end-user.

The global gas sensor market is bifurcated based on gas type into carbon monoxide, methane, hydrogen, ammonia, oxygen, and others.

The methane segment is the highest contributor to the market and is estimated to grow at a CAGR of 6.45% during the forecast period. Due to their benefits, such as a broad range of operations and excellent efficiency in a changing environment, methane gas sensors are widely employed in various industries. Methane concentrations between 300 parts per million (ppm) and 10,000 ppm can be detected by gas sensors (ppm). For the detection of methane gas leakage, this range is acceptable. These sensors offer a quick and real-time response, wide-range detection, and high sensitivity. Gas leak alarms, industrial combustible gas detectors, portable gas detectors, and home gas leak detectors all use methane gas sensors.

Carbon monoxide is a combustible gas that is tasteless, colorless, and somewhat denser than air. Both humans and animals are said to be poisoned by this gas. It is made up of carbon and oxygen atoms. When carbon-containing materials undergo partial oxidation, such as when an engine is running, iron is being melted, coal gas is being used, or a stove is being used, carbon monoxide is created. In many nations throughout the world, carbon monoxide poisoning is regarded as the most prevalent kind of lethal air poisoning. To lessen exposure to carbon monoxide gas, a number of businesses throughout the world are producing gas sensors or gas detectors. Carbon monoxide is detectable by gas sensors at concentrations between 10 and 10,000 ppm.

The petroleum and chemical industries are the primary hydrogen users in considerable quantities. The two main uses of hydrogen are the generation of ammonia and the processing of fossil fuels.
