Abstract
An electrochemical gas sensor is provided for a motor vehicle. The gas sensor contains a digital controller and a detection circuit. The digital controller captures, by a feedback input, a value of the voltage applied to the inside of the gas sensor cell. The output of the digital controller provides a control value for the current flowing in the gas sensor cell. The detection circuit is used to detect the properties of the gas sensor cell and to adjust the dynamic control properties of the digital controller corresponding to the properties of the gas sensor cell.
