Abstract
Provided is a gas sensor system with a gas sensor, and a microprocessor programmed to control the gas sensor with at least two operational modes. The first operational mode controls the gas sensor from a baseline level through analyte detection. Upon initiation of the recovery phase after analyte withdrawal, the gas sensor system switches to the second operational mode, which changes conditions of the gas sensor to (i) accelerate removal of the analyte from the gas sensor and (ii) accelerate recovery of the gas sensor output towards the baseline level. When no further analyte is detected, the gas sensor switches back to the first operational mode or to an additional operational mode to complete recovery.
