Gas Sensing Systems and Methods of Operation Thereof

A sensor device comprising:

• a gas sensor disposed on a substrate, the gas sensor being configured to measure first sensor data points and second sensor data points;
• a reference sensor disposed on the substrate and adjacent to the gas sensor, the reference sensor being configured to measure first reference sensor data points and second reference sensor data points,
• a processor operatively coupled to the gas sensor and the reference sensor;
• and
• a memory storing a program to be executed by the processor, the program comprising instructions for performing the following steps in real-time,
• adjusting the second sensor data points using the first sensor data points, the first reference sensor data points, and the second reference sensor data points to obtain corrected sensor data points, and
• determining sensed values from the corrected sensor data points.

• determining a correlation between the first sensor data points and the first reference sensor data points,
• determining instantaneous baseline values for each of the second sensor data points using the correlation,
• subtracting the instantaneous baseline values from the corresponding second sensor data points to obtain corrected sensor data points, and
• determining sensed values from the corrected sensor data points.
