A method for characterizing the state of an alcohol sensor comprising prompting an individual to provide a biological sample at a first time point generating an alcohol signal upon reception of the biological sample from the individual an environmental metric associated with the fuel-cell alcohol sensing device at a second time point contemporaneous with the first time point determining a degeneration parameter of the fuel-cell alcohol sensing device extracting a correction factor upon implementing a rule with the environmental metric and the degeneration parameter and at the remote computing system, generating a notification based upon the correction factor exceeding a threshold correction factor.
