Hello Mankurt,
Thanks for your question.
There is deviation for each sensor. Therefore, the characteristic value for each sensor could be different.
For example, we mention sensor to sensor deviation could be +- 15%. (Check Table 3.)

To get more accurate AI config file for all sensors, please gather data as many as sensors you have, then train it.
Then, you can get more general trend of specific gas or some chemical thing, then you can get it more accurately.
Please let me know if you have any quesitons.
Thank you.
