Abstract

A method of operating a sensor system including at least one sensor for detecting an analyte gas and a control system includes electronically interrogating the sensor to determine the operational status thereof and upon determining that the operational status is non-conforming based upon one or more predetermined thresholds, the control system initiating an automated calibration of the sensor with the analyte gas or a simulant gas.

Claims (4)

1. A method of operating a sensor system including a first sensor to detect a first gas analyte and a control system, comprising:

electronically interrogating the first sensor to determine the operational status thereof; and

based upon the results of the electronic interrogation, the control system switching the first sensor from detecting the first gas analyte to detecting a second gas analyte that is different from the first gas analyte.

2. The method of claim 1 wherein the first sensor is an electrochemical sensor.
