Abstract
The implementation of gas sensors in automotive environments aims to improve the air quality for vehicle occupants. These sensors provide output signals corresponding to the gas concentration of the prevalent pollutant and the degree of odor contamination. This output signal is primarily used for the automatic recirculation control of the vehicle’s Heating, Ventilation, and Air Conditioning (HVAC) system.
This paper outlines the requirements of solid state gas sensors for use in automotive air quality applications. 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 must fulfill strict cost requirements and meet high standards of reliability and quality.
Based on the example of a metal oxide semiconductor gas sensor, the technical specification, data interpretation, application criteria, and automotive suitability are demonstrated. Furthermore, a brief overview of the use of solid state gas sensors for detecting the indoor cabin air quality via odor pattern recognition is given.
