Abstract

A method can be performed by adjusting a temperature of a gas sensor to a first temperature value for a first period of time and a second temperature value for a second period of time. The gas sensor signal may be measured during the first period of time to determine a first signal value and during the second period of time to determine a second value. Then concentration information for at least one gas is calculated according to the first signal value and the second signal value. While the gas sensor signal may include information about a presence of a first gas and a second gas the concentration information for the at least one gas may not substantially include concentration information for the second gas.
