    • A gas sensor, suitable for use under non-steady state conditions, has a gas-sensitive resistor with pairs of electrodes which either have different spacings between the electrodes of a pair, or comprise a pair at the active surface and further pairs buried in the resistor at different distances from the active surface. The sensor can be used in place of a sensor array, and is coupled to a processor for processing the resistance signals to detect and/or measure at least one target gas. The sensor is self-diagnostic, and factors such as relative humidity and ambient oxygen, that can otherwise affect the readings, can be compensated for without the aid of additional sensors for that purpose. An operating line or surface is defined for the expected behavior of the sensor, and the resistance signals from the electrode pairs are processed so at to give information which is then related to the operating line or surface, so as to reveal, in terms of error indications, any malfunction of the sensor and/or the presence of specific constituents of the gas mixture.
