The rise in air pollution is expected to drive the growth of the gas sensor market going forward. Air pollution refers to the presence of harmful substances in the atmosphere that can negatively affect human health and the environment. Air pollution is increasing due to the rapid expansion of industrialization and vehicle emissions. Gas sensors are devices used to detect the presence and concentration of specific gases in the air. They can also identify gas leaks and help prevent hazardous situations. For example, in October 2025, according to the World Meteorological Organization (WMO), a Switzerland-based specialized agency, the global average atmospheric CO₂ concentration reached 423.9 parts per million (ppm) in 2024, representing an increase of 3.5 ppm from 2023, the largest annual rise ever recorded. Therefore, the increasing air pollution is fueling the growth of the gas sensor market.

Leading players in the gas sensors market are focusing on developing innovative solutions such as photoionization detector (PID) sensors to achieve ultra-sensitive detection of volatile organic compounds (VOCs) and toxic gases for industrial safety and environmental monitoring applications. A PID sensor uses ultraviolet (UV) light to ionize gas molecules, generating a current proportional to the gas concentration - offering higher sensitivity, faster response, and a broader detection range compared to traditional electrochemical or metal-oxide sensors. For instance, in October 2024, Alphasense Ltd., a UK-based gas sensor manufacturer, launched the PIDX series, an advanced range of PID sensors designed for precise VOC measurement. The product features multiple detection ranges from 0-4 ppm to 0-10,000 ppm, improved baseline stability across temperature and humidity variations, enhanced sensor repeatability, and integrated fault detection for maintenance alerts, making it well-suited for both portable and fixed gas detection systems.

In December 2023, Amphenol Corporation, a US-based manufacturer of electronic connectors, acquired PCTEL for an undisclosed amount. This acquisition is intended to strengthen Amphenol's portfolio in wireless technology solutions, including IoT devices, antenna systems, and test and measurement products, by incorporating PCTEL's expertise into its global operations. PCTEL is a US-based company specializing in test and measurement products and antenna systems, which also offers gas sensors as part of its Industrial IoT product lineup.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have influenced the gas sensor market by increasing costs for imported semiconductors, MEMS components, catalytic elements, infrared modules, and calibration materials used in sensor production. Industrial, automotive, consumer electronics, and healthcare sectors in North America, Europe, and Asia-Pacific face higher production and deployment costs due to cross-border component dependencies. Nonetheless, tariffs are driving regional manufacturing investments, promoting local sourcing strategies, and accelerating innovation in low-cost, high-performance gas sensing technologies, strengthening long-term supply chain stability.
