Adaptive sensor temperature control for fast recovery

A gas sensor system comprising:

• a gas sensor for detecting an analyte;
• and
• a microprocessor programmed to control the gas sensor with at least two operational modes,
• wherein,
• a first operational mode controls the gas sensor from a baseline level through analyte detection and initiation of a recovery phase upon analyte withdrawal, and
• a second operational mode temporarily changes conditions of the gas sensor after the initiation of the recovery phase to (i) accelerate removal of the analyte from the gas sensor and (ii) accelerate recovery of the gas sensor output towards the baseline level, wherein the microprocessor switches the gas sensor from the first operational mode to the second operational mode in real-time and the temporary conditions of the second operational mode prevent the gas sensor from detecting the analyte during the second operational mode.
