Gas Sensor Market Growing Demand and Huge Future Opportunities by 2030


The global market size of the gas sensors was valued at USD 823.1 million in 2020 and is projected to reach  USD 1,336.2 million by 2027, registering a CAGR of 6.4% from 2021 to 2027. A gas sensor is a device that identifies the concentration of gases or the presence of gas in the environment or atmosphere. The gas sensor’s concentration of gases in the atmosphere displays a modification in the resistance of the material used in the sensor, which is used to measure the voltage. Based on the change in the voltage value, the concentration and type of gas are detected. Gas sensors detect volatile compounds such as air quality and gases. These sensors measure and detect the concentration of gas and can change the concentration of analyte gas into an electrical signal or electronic. These sensors are used in several industries ranging from aerospace, medicine, energy, and defense & military.

Gas sensors are smart electronic devices used to detect and identify various types of combustible and non-combustible gases in an indoor or outdoor environment. The sensors are interfaced with a control system, so it can detect leakage and provide the initiating signal to shut down or raise the alarm. Gas sensors are majorly used to detect gases such as carbon monoxide, methane, hydrogen, ammonia, oxygen, and others in applications such as infrared sensors, photoionization sensors, and electrochemical sensors. These gas sensors are deployed in various end uses such as defense and military, industrial automotive, among others.

Global Gas Sensor Market Dynamics

Drivers: Increasing need for air quality monitoring in smart cities

Air pollution is a major problem worldwide. According to the World Health Organization, urban areas have recorded around 80% of air pollution levels that are beyond the acceptable values. Hence, there is a rising concern for controlling air pollution levels worldwide. Gas sensors are used in smart cities to monitor the air quality in urban areas as well as residential spaces. IoT-enabled gas sensors are used to monitor the pollution levels especially for smart infrastructures. These smart devices detect pollution levels and send data to the IoT cloud.

Air quality monitoring is finding its applications in areas such as parks, markets, public venues, and other major city venues. The increasing need to monitor and control air quality and pollution levels in smart cities and smart infrastructures is driving the market growth of gas sensors to a certain extent.

Restraints: High initial price of the device

The addition of sensors helps to increase the automation in the electronic devices. However, it incurs an extra cost and afterward is avoided in cost-effective end uses. The incorporation of sensors facilitates some extra features and makes the devices more automated, although, some additional cost and afterward it is avoided in the cost-effective application. These devices are continuously used for a long time, such as laptops, cameras, and smartphones sensors, creating heating issues and decreasing the sensors’ life as these devices have components that are temperature sensitive. The devices which use the battery as the power source, sensors reduce their battery life as they rely on the device battery for their operation.
