Air Quality Sensors Market Report 2026

The air quality sensors market size has grown strongly in recent years. It will grow from $5.67 billion in 2025 to $6.15 billion in 2026 at a compound annual growth rate (CAGR) of 8.5%. The growth in the historic period can be attributed to rising urban air pollution levels, implementation of early environmental monitoring regulations, growth in industrial emissions monitoring, increasing public health awareness, expansion of government-led air quality programs.

The air quality sensors market size is expected to see strong growth in the next few years. It will grow to $8.18 billion in 2030 at a compound annual growth rate (CAGR) of 7.4%. The growth in the forecast period can be attributed to stricter global air quality regulations, growing adoption of smart city infrastructure, increasing deployment of iot-based sensors, rising demand for real-time environmental data, expansion of indoor air quality monitoring. Major trends in the forecast period include ai-enabled real-time air quality analytics, iot-integrated smart air monitoring networks, data-driven environmental compliance systems, automated industrial emissions monitoring, cloud-based environmental data platforms.

The rising incidence of airborne diseases and related fatalities is expected to drive the growth of the air quality sensors market in the coming years. Airborne diseases are caused by bacteria or viruses that primarily spread through tiny respiratory droplets. Their increase is influenced by factors such as higher population density, international travel and migration, and the emergence of antimicrobial-resistant strains. Air quality sensors are employed to detect concentrations of airborne pollutants, as these devices are designed to identify and display levels of specific pollutants, such as particulate matter (PM), in indoor environments. For instance, in September 2024, the Institute for Health Metrics and Evaluation, a US-based health research organization, reported that by 2050, antimicrobial resistance (AMR) could directly cause 1.91 million deaths, representing an almost 70% annual increase compared to 2022. Therefore, the rising prevalence of airborne diseases and fatalities is driving the growth of the air quality sensors market.

Key players in the air quality sensors market are concentrating on developing advanced solutions such as outdoor air quality monitoring platforms to gain a competitive advantage. These platforms encompass comprehensive systems integrating various air quality sensors, data collection methods, and analysis tools to continuously monitor and evaluate ambient air quality in specific locations or larger geographical areas. For example, in March 2023, Attune Inc. launched an air quality monitoring (OAQ) kit, a sensor-based platform for outdoor air quality monitoring. This versatile technology solution with multiple sensors detects various outdoor air pollutants such as temperature, humidity, volatile organic compounds (VOCs), particulate matter (PM0.3-1.0, PM2.5, PM10), carbon dioxide (CO2), carbon monoxide (CO), hydrogen sulfide (H2S), nitrogen dioxide (NO2), ozone (O3), and sulfur dioxide (SO2). The platform is customizable based on specific customer requirements.

In November 2023, Groupe TERA, a France-based real-time air quality measurement and analysis company, acquired a significant stake in OMWAVE for an undisclosed amount. Through this acquisition, Groupe TERA aims to strengthen its sensor value chain from design to production and expand its capacity for OEM air quality sensors. OMWAVE is a France-based company that provides solutions related to air quality.

Major companies operating in the air quality sensors market are Bosch Sensortec GmbH, Siemens AG, Haier Group Corporation, Schneider Electric SE, Valeo AG, Amphenol Corporation, Renesas Electronics Corporation, SUEZ SA, Honeywell International Inc., Sensata Technologies Inc., Vaisala Corporation, Sensirion AG, FIGARO Engineering Inc., Paragon AG, Purelogic Labs, Alphasense Ltd., MetOne Instruments Inc., Eltako GmbH, Birdi Inc., AireBeam Communications, Kaiterra Inc., Foobot, AirGuard HK Ltd, PurpleAir Inc., Aeroqual Limited.

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 impacted the air quality sensors market by increasing the cost of imported sensing components, semiconductors, and calibration equipment, affecting overall manufacturing and deployment timelines. These cost pressures are most evident in industrial, government, and smart city deployments, particularly in Asia-Pacific and North America where large-scale sensor networks are installed. Companies are responding by localizing production, diversifying supplier bases, and optimizing sensor designs to reduce dependency on tariff-affected imports. In some regions, tariffs have encouraged domestic manufacturing and strengthened local sensor ecosystems, supporting long-term market resilience.

This air quality sensors market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenarios of the industry.

Air quality sensors are devices designed to measure the concentration of pollutants and other harmful particles present in the air. They detect a range of pollutants, including particulate matter, carbon monoxide, and nitrogen dioxide, providing real-time data that aids in monitoring air quality levels and supporting environmental assessment and management efforts.

The primary categories of air quality sensors include signal-gas monitoring systems and multi-gas monitoring systems. Signal-gas monitoring systems are technologies that detect and measure specific gases or chemical compounds in the air, typically utilized for safety or environmental monitoring purposes. In terms of portability, there are various types such as portable air quality sensors and fixed air quality sensors, both used for monitoring different pollutants such as chemicals, particulate matter, and biological agents. These sensors find application across various sectors, including government agencies, petrochemical industries, power plants, and residential areas.North America was the largest region in the air quality sensors market in 2025.
