Automotive suitability of air quality gas sensors

This work outlines the technical and environmental requirements of sensors for use in automotive applications and describes the features of automotive air quality gas sensors as an example. Implementing these sensors in an automotive environment poses a number of challenges, due to the wide range of possible temperature, humidity and vibration profiles. Additionally, the sensors are required to fulfill substantial reliability, quality and cost requirements. Based on the example of a metal oxide semiconductor gas sensor the technical specification and the qualification criteria for automotive capability are presented.
