Claim 0:
1. A breath sensor apparatus, comprising:
a sampling unit having a housing configured to receive a sample breath from a user;
a sensor positioned within the housing and in fluid communication with the sample breath when received within the housing;
a processor in electrical communication with the sensor,
wherein the processor is configured to determine a dissipation time when the sensor is exposed to a constant concentration level of carbon monoxide (CO) detected from the breath sample down to an ambient level of CO detected,
wherein the processor is further configured to calculate a time constant based on the dissipation time and a reduction from the constant concentration level to the ambient level; and
wherein the processor is further configured to apply the time constant to a transient response of the sensor to account for drift in calibrating the sensor.
