The airflow sensor market size is expected to grow from US$ 2.41 billion in 2022 to US$ 3.50 billion by 2030; it is estimated to register a CAGR of 4.8% from 2022 to 2030.

Analog airflow sensors provide an analog interface for reading airflow over the specified full-scale flow span and temperature range. These sensors respond quickly to air or gas flow owing to their thermally isolated heater and temperature-sensing elements. These sensors have various benefits, such as being customizable for specific end user needs, high sensitivity at very low flows, allowing a customer's application to detect the presence or absence of airflow, high stability, reducing errors due to thermal effects and null shift to provide accurate readings over time, low-pressure drop typically improves patient comfort in medical applications. Also, it reduces noise and system wear on other components, such as motors and pumps. These benefits are, therefore, catalyzing the analog airflow sensor market growth.

Based on type, the airflow sensor market is bifurcated into volume airflow sensors, mass airflow sensors. Mass airflow sensors are most broadly used in the automobile industry to detect the mass flow of air that enters the vehicle's engine and the fuel injection amount. Mass airflow sensors play such an important role in engine performance that badly performing sensors can result in entirely inaccurate air/fuel ratios that can harm engines, increase the number of pollutants the vehicle generates, and maximize fuel consumption. Mass airflow sensors are useful diagnostic and monitoring tools for any application dependent on particular gas flow rates for functioning. These sensors are often easy to connect to monitoring equipment and data logging. Furthermore, these sensors can be connected to feedback loops to ensure constant mass airflow rates, which is necessary for most medical applications of mass airflow sensors. Due to all these benefits, the adoption of mass airflow sensors is increasing, thereby boosting the airflow sensor market growth.

Based on application, the airflow sensor market is segmented into automotive, aerospace, manufacturing, power and utility, others. Airflow sensors play a vital role in aerospace applications, ensuring accurate airflow measurement for engine performance and control. These flow sensors utilize no moving parts and ultra-reliable thermal dispersion flow measurement technology to detect a flow rate above or below a predetermined set point at the sensing location. They are applied to signal low/high flow alarm conditions in the air or liquid fluid flows throughout the aircraft. These sensors are directly installed into piping or ducting on commercial and military aircraft and spacecraft. Airflow sensors are widely used in the aerospace industry. Thus, the demand for airflow sensors is increasing with the growing aerospace industry.
