Global Carbon Dioxide Gas Sensor Market Growth 2025-2031

The global Carbon Dioxide Gas Sensor market size is predicted to grow from US$ 993 million in 2025 to US$ 1525 million in 2031; it is expected to grow at a CAGR of 7.4% from 2025 to 2031.

Carbon Dioxide (CO₂) Gas Sensor is a sensor used to detect and measure the concentration of carbon dioxide gas in the air. It provides real-time data by sensing the concentration changes of carbon dioxide in the environment. It is widely used in environmental monitoring, industrial safety, air quality control, smart building systems and other fields.

The CO2 gas sensor market has developed rapidly in recent years. With the increasing demand in environmental protection, smart home, industrial automation and air quality control, the market size and application have gradually expanded. CO2 gas sensors are mainly used to detect and monitor the concentration of carbon dioxide in the air, and are widely used in environmental monitoring, smart buildings, agriculture, industrial production, medical health and other fields. Its core function is to monitor the concentration of carbon dioxide in the air in real time, timely feedback environmental changes, and ensure the safety of air quality and working environment.

At present, the market demand for CO2 gas sensors is mainly driven by the following factors. First, with the increasing global attention to environmental protection and air quality, especially in the context of accelerated urbanization, air pollution has become more prominent. As the main component of greenhouse gases, the concentration of CO2 is closely related to the atmospheric environment. Therefore, the demand for monitoring CO2 concentration in cities and industrial areas is increasing. Secondly, the development of smart buildings and smart homes has also promoted the widespread application of CO2 sensors. In smart homes, by monitoring the concentration of carbon dioxide in the air, the ventilation system can be adjusted to ensure indoor air quality, and energy efficiency can be optimized through data analysis to improve living comfort. In addition, public places such as smart office buildings, schools, and hospitals are also paying more and more attention to air quality, and the application demand of CO2 gas sensors in these fields is increasing.

In the industrial field, CO2 sensors are widely used for gas monitoring in the production process, such as food processing, beverage production, chemical industry and other industries. Monitoring CO2 concentration is crucial to ensure the safety of the production process and improve production efficiency. Especially in greenhouse agriculture, reasonable CO2 concentration control can significantly improve crop photosynthesis and promote plant growth. Therefore, for agricultural producers, the demand for CO2 sensors is also gradually increasing.

The CO2 gas sensor market is undergoing rapid technological changes and demand growth. With the strengthening of environmental protection regulations, the development of intelligent technology, and the increase in people's attention to air quality, the application of CO2 sensors will become more and more extensive. In the future, CO2 sensors will be more intelligent, accurate, low-power, and able to adapt to more complex application environments. With the continuous innovation of technology and the expansion of market demand, the market for CO2 gas sensors will usher in a broader development space.
