Can anyone send me where I can fina a sensor which detects methane flame?

Google ?
You are going to have to much better explain your application. Older furnaces (residential) for example used a thermocouple to detect a pilot flame. Large furnaces and combustion chambers used what we called a flame rod. You may want to research the different types of flame sensors and determind which is best suited for your application, then worry about an interface.

Do you want a physical sensor (thermocouple) or something more like an IR sensor? I don't know of anything that will determine the fuel behind the flame, differentiating methane from wood or paper.

What color of flame does your methane produce?

Anyone else get a message from the OP requesting they answer his question?

Nope. Things are pretty simple, define your application. If I do get a PM I will likely just politely redirect them to the open forums.

Me neither. Must be some homework for school.

Color is blue. Wave length of this flame is 250 - 30 nanometers, versur lpg flame which is 1000 nanometers.

Application is to detect if a flame is burning or not. I'm my city we have methane distribution.

Ok. Now, is there any other light that might interfere with the sensor being ably to detect the flame?

Oter light surce is ambient natural and artificial ligtning. Il is a kitchen.

How will you keep the natural and artificial light from being seen by the sensor?
Seems your problem is a bit more involved than just finding a sensor to see a methane flame.

Why not use a thermocouple placed where the flame is supposed to be? The temperature will tell you whether there's a flame or not. It may not be able to tell you whether it's methane or that the utility quietly switched to propane, if that's what you're after.
