Hello you all. I'm working right now with a Cooking Gas detector with arduino and GSM module and I have a doubt. Could you tell me which sensor is the best for this purpose, MQ-2 or MQ-6?. Thanks BTW.
Do you mean the propane or natural gas or the resulting cooking fumes?
Tom's list misses a couple of gases used for cooking eg co (aka town gas)or even H2.
So the question is what are you looking for?
I need it for natural Gas tom
Natural gas - methane CH4 Normal a scent is added to this so that people can smell it.
So you are looking for a methane sensor or maybe something that can pickup the additive.
May google be with you.
