Market Drivers
Stringent regulatory policies for workplace safety across developed economies are a major driver for the gas sensor market. Governments have established regulatory frameworks mandating adoption of gas detection solutions in industries dealing with hazardous gases. For instance, Occupational Safety and Health Administration (OSHA) in the U.S. has implemented stringent monitoring standards for toxic and combustible gases that is bolstering the demand for gas sensors.

Market Restraints
High cost associated with maintaining and calibrating gas detection equipment poses a major challenge especially for price-sensitive small and medium enterprises. Furthermore, limited lifetime of gas sensors increases the maintenance and replacement costs over time, which could hamper the growth of gas sensor market to some extent.

Segment Analysis
The gas sensor market is segmented by technology type into electrochemical, semiconductor and catalytic sensors. The electrochemical segment dominates the market currently owing to its low cost and better sensitivity for toxic gases like carbon monoxide. It is widely used in the automotive industry for vehicle emission monitoring. However, semiconductor sensors are growing at a faster rate due to their high sensitivity and stability for detection of a wide range of gases.

Global Analysis
Regionally, Asia Pacific holds the largest share of the gas sensor market currently due to the presence of a large automotive manufacturing base and strict emission monitoring regulations in countries like China, Japan and India. The region is expected to witness the highest growth during the forecast period owing to increasing industrialization and implementation of strict environmental protection policies. Europe and North America are also significant markets due to stringent workplace safety rules and urban population exposure monitoring initiatives. These regions have a high demand for photoionization detectors and open path monitoring systems for urban air quality management programs.
