Automotive requirements for sensors using air quality gas sensors as an example

This work outlines the 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, atmospheric pressure, 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.
