Hello to everyone.I am interested if there is MQ2 or MQ135 sensor alternative which works on 12V ?

Have you heard about the XY-problem ? https://xyproblem.info/

You are trying to solve a problem that you have created yourself and isn't a problem after all.

Maybe you want to ask a different question. For example: Are there gas sensors similar to the MQ2 and MQ135 that are embedded in a chip and are not so power hungry ?

A 12V to 5V stepdown converter could be used to power an MQx.

Maybe.I have an idea.12 to 5V would power MQx and PCB can be used with 12V and signal output from MQx should trigger the CPU.I will test it.Sorry for late reply

If you are going to need a lot of them you can design your own sensor board with the interface you want. That board will still require the same power + the power needed for the interface.
