I use the MQ-136 gas sensor module. I have a problem in detecting H2S gas. I don't get accurate h2s gas in PPM. Does anyone have a code program for this module? Please help me.
I also have a problem in calibrating the MQ 136 sensor. The PPM value in H2S gas is not detected accurately. can anyone help me
Can you please post your complete code?
How do you know you are not getting the right ppm reading?
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
this is my code. try to correct, where is the error?

Why don't you answer the other two questions of #2, or do you really think that is not relevant to your code?
I think it's relevant and I try to answer question # 2, and that's the code I'm trying to share.
Code is one thing, but it's meaningless without a circuit and without knowing why you think you get the wrong numbers (so you tell what you get and what you expect to get) - i.e. the other two questions from #2 (don't stop reading after you find a "?").
Sorry. Let me know. What should I do? do I need to share my series. the MQ 136 series consists of Vcc, Gnd, A0 and D0.
I have to add I'm getting quite tired of having to suck information out of you. Remember you're asking for FREE help. All you give is a piece of code saying "it's not good". You really think that is enough to get an idea on WHY?
So, last chance: how do you know you are not getting the right ppm reading?
Where is the sketch/CAD drawing of YOUR circuit?
