Hi,
I am trying to develop a Gas detector module to detect Methane (CH4) gas.
I am using the 'ezPyro CH4 Gas sensor' (SMD).
Now, the difficult part is resourcing the required Methane Gas. I believe I need small amount of Methane gas for lab testing. But I coudn't find any such supplier who sells such small amount in a cylinder.
Another issue is, how would I be able to control the amount of gas I would be supplying to my testing chamber in terms of PPM? I want to know exactly what amount of PPM is getting supplied to the gas chamber thus I can form a calculation from the sensor's output to reflect the amount of gas present in the air.
This sensor's output is in current. So, I'm planning to calculate the PPM of the given gas in terms of the current I will be getting at the output.
So please suggest me how can I perform the testing successfully.
Regards
