IAQ Sensor Calibration: Does ‘Software Calibration’ Really ...

For example, a correction factor can be used to make a TVOC sensor map to a specific mix of pollutants in a particular environment. Instead, we are referring to claims that ‘software calibration’ can replace physical sensor calibration for long-term accuracy. The term ‘software calibration’ is not entirely correct. By definition, a device cannot be calibrated without being compared ...

How Does a TVOC Sensor Actually Work? - Kaiterra

The change in resistance across the surface of the sensor is directly proportional to the change in concentration of the target gas (es). The exact degree to which the resistance will change (that is, the ratio or equation that explains this relationship) may vary with the exact gas present in the space.
