Abstract
The paper presents a spectroscopic gas sensor system for measuring carbon dioxide (CO2). The Bi-Source design consists of two infrared (IR) sources with one common detector and maintains high accuracy in the entire range of the harsh automotive environmental conditions over 6000 h operating lifetime. The influence of the atmospheric pressure on the gas sensor output data is compensated with an implemented MEMS piezo resistive pressure sensor.
