The gas sensor market will grow at a CAGR of 13.77% from USD 1.033 billion in 2025 to USD 1.969 billion in 2030.
The gas sensor is used for safety purposes to detect toxic or combustible gases, such as Carbon Monoxide, in both residential and industrial locations. These sensors detect the concentration of harmful gases and aid in preventing poisoning in industrial environments.
Technology innovation, primarily due to enhanced manufacturing processes and embedded electronics coupled with occupational safety and health regulations, is expected to drive the Gas Sensor market. Furthermore, the development of wireless sensors coupled with increasing awareness regarding air quality will further add to the growing demand for these sensors over the forecast period.
Gas sensors find application in constantly controlling and monitoring gas emissions from processes of various industries, ranging from domestic to industrial. Further, the growing demand to control harmful emissions from crucial industries also bodes well for the growth of the market. Technological advances and innovations are also expected to aid gas sensor manufacturers in developing smart gas sensors. Several companies have also been developing drone-based gas leak detection systems for the provision of better safety for the operators of pipelines across the world.
Strict government regulations for the reduction of car emissions are expected to propel the demand during the forecast period. Rules and regulations are being imposed by governments across the world on the emission of gas from automotive vehicles. The imposition of limitations on gas emissions from vehicles is expected to create demand for gas sensors, as it lowers atmospheric pollution and increases fuel efficiency.
Several industries, such as oil & gas, chemical, and power, utilize these gas sensors for the detection of the presence of various combustible and toxic gases. A vast number of gases, such as carbon monoxide, hydrocarbons, carbon dioxide, and ammonia, are released into the air by these industries. An excess of emissions of these gases can adversely affect human health.
Further, for power generation, methane is being used widely. It is a greenhouse gas that is extremely inflammable and forms explosive mixes in the air if it leaks are not detected properly. Thus, new sensor technologies are being developed, such as substance-specific electrochemical sensors and NDIR (Non-dispersive Infrared) sensors that are used for the detection of methane and other gases in industries.
Despite ongoing advancements, certain technologies face challenges in attaining the necessary sensitivity and selectivity for detecting specific gases within intricate environments. Miniaturization efforts aimed at wearable and Internet of Things (IoT) applications may compromise sensitivity and accuracy.
Advanced technologies such as infrared and multi-gas sensors may incur high costs, particularly for small-scale applications. This expense can pose a barrier to adoption, particularly in industries sensitive to costs.
The Gas Sensor Market is segmented by Technology into Electromechanical, PID (Photoionization Detectors), Catalytic, Infrared (IR), and Others. Electromechanical sensors are extensively utilized across diverse industries owing to their affordability, reliability, and ease of use. They find common applications in air quality monitoring, leak detection, and combustion control.
PID sensors are primarily employed for detecting volatile organic compounds (VOCs) due to their high sensitivity and selectivity. They are utilized in environmental monitoring, industrial process control, and leak detection for hazardous gases.
Catalytic sensors are commonly utilized in automotive applications such as exhaust gas sensors, as well as in industrial process control and safety monitoring.
Infrared sensors are deployed in various applications requiring high accuracy and selectivity, such as medical gas monitoring, environmental monitoring, and industrial process control.
The other category encompasses sensors utilized in specialized applications requiring unique functionalities or addressing limitations of traditional technologies.
It is expected that North America will maintain a substantial portion of the gas sensor market. The implementation of government regulations aimed at ensuring workplace safety is also contributing to the expansion of the carbon monoxide sensors market.
For example, incidents of carbon monoxide poisoning in the US have prompted the government to distribute carbon monoxide detectors across various states. As a result, schools in states like Connecticut, Maryland, Illinois, California, and Maine are mandated to install carbon monoxide detectors in their buildings.
