| Zusammenfassung: | Disclosed herein is a device and method for converting the resistances of an array of metal oxide sensors into digital signals, wherein the sensors respond to the concentration of gases surrounding the sensor array. The device includes an electronic excitation device that provides an excitation voltage to the sensors; analog-to-digital signal conversion devices that convert the resistances of the sensors to digital signals; and means for calculating gas concentrations from the digital signals. |
