Abstract
A gas sensor control apparatus () including a control section () which executes a first receiving process (STEP) for receiving a first detection result output from a mixed-potential-type ammonia detection section () for detecting ammonia contained in a gas under measurement and corresponding to the concentration of ammonia, a second receiving process (STEP) for receiving a second detection result output from an oxygen detection section () for detecting oxygen contained in the gas under measurement and corresponding to the concentration of oxygen, a first concentration calculation process (STEP) for calculating a first ammonia concentration of the gas under measurement based on the first detection result and the second detection result, and a pressure correction process (STEP) for correcting the first ammonia concentration based on pressure information obtained from an external device (), thereby obtaining a second ammonia concentration of the gas under measurement.
