I recently acquired this MQ136 H2S gas sensor and was curious about the code that was in the video on the product page. I couldn’t find it on Github, so I decided to just copy the code from the video but the value used to calculate R0 (R0 = RS_gas/9.9) was for the MQ9 and couldn’t find a value that seemed to be interchangeable in the datasheet provided on the product page of the MQ 136 i also referenced the datasheet of the MQ9.
I was curious if anyone might know where I could find this code and the values for the MQ136 that could be interchanged in the code to find the resistance value. Any other information about calibrating the gas sensor would be greatly appreciated since I have never calibrated a gas sensor before.
Thank you,
