Gas sensors are electronic devices that detect the presence and concentration of gases in the environment. They work by converting chemical or physical changes caused by gas molecules into electrical signals, allowing for the measurement and monitoring of specific gases in real time. The main purpose of gas sensors is to ensure safety, environmental monitoring and process control by detecting hazardous or target gases such as carbon monoxide, methane, or oxygen.
The gas sensors market consists of sales of gas sensors by entities (organizations, sole traders and partnerships) that is primarily utilized by industrial plants, laboratories, residential areas and public spaces. Complementary products to gas sensors encompass alarm systems, ventilation controls and air purification systems. In contrast, substitute technologies might include manual gas detection methods or alternative sensor types, though these often lack the precision and real-time monitoring capabilities of modern gas sensors.
The global gas sensors market was valued at $1,711.90 million in 2019 which grew till 2024 at a compound annual growth rate (CAGR) of more than 6.00%.
Rise In Oil And Gas Industry
The rise of oil and gas Industry propelled the growth of the gas sensor market in the historic period. As the oil and gas sector has expanded to meet global energy needs, safety concerns related to gas leaks and emissions have become paramount. Gas sensors are essential in this industry for monitoring hazardous gases such as methane, hydrogen sulfide and carbon monoxide to prevent accidents and ensure worker safety. For instance, in May 2023, according to the Kansas Geological Survey, a US-based division of the University of Kansas dedicated to geological studies and related activities, the count of permitted wells accounted for 366, with the drilling of 34 fresh oil wells and a single new gas well. Furthermore, a substantial surge in permitted wells was observed, reaching 1,684, accompanied by the drilling of 837 new oil wells and 79 gas wells in 2022, compared to 1,290 total permitted wells in 2021. Additionally, in December 2022, according to Energy Information Administration (EIA), a government agency, global oil production accounted for 95.70 million barrels per day in 2021, an increase of 1.96% compared to 93.86 million barrels per day in 2020. In addition, the US accounted for the largest share, with 20% of the total oil produced worldwide. Therefore, rise of oil and gas industry supported the growth of the gas sensor market.
Enhanced Flame Sensors For Safer Gas Turbine Environments
Major companies operating in the gas sensor market are focused on the integration of new technologies, such as enhanced flame sensors for safer gas turbine environments. These advanced flame sensors can more accurately detect the presence of a flame within the combustion chamber, ensuring that the turbine operates within safe parameters. This is particularly important in gas turbines, where the stability of the flame is critical for maintaining efficiency and preventing potentially hazardous situations like flameouts or unburned fuel emissions. For example, in May 2025, Baker Hughes, a US-based energy technology company, launched an advanced flame detection technology, Flame Tracker Increased Low Gain (ILG), designed to enhance flame sensing capabilities on gas turbines. Flame sensors are crucial safety devices in gas turbines that detect the presence of a flame in the combustor section. They provide early warnings if the flame is lost or unstable, triggering a shutdown sequence to prevent turbine damage and minimize hazards, including explosions from unburned fuel buildup.
The global gas sensors market is fairly concentrated, with large players operating in the market. The top ten competitors in the market made up to 25.44% of the total market in 2023.
