A combustible gas sensor includes at least a first sensing element comprising a first conductive element having, for example, an average diameter less than 20 μm in electrical connection with electronic circuitry. The combustible gas sensor further includes a first support element having a first anchored end, a second anchored end and an extending intermediate section between the first anchored end and the second anchored end, the extending intermediate section providing support for the first conductive element. Another combustible gas sensor includes a first sensing element and a second sensing element. The first sensing element includes a first catalyst support member having a volume less than a sphere having a diameter of 500 μm. The second sensing element includes a second catalyst support member having a volume less than a sphere having a diameter of 500 μm. The combustible gas sensor further includes electronic circuitry that is adapted to cycle between a first mode in which the first sensing element is operated in a higher power mode and the second sensing element is operated in a lower power mode and a second mode in which the second sensing element is operated in a higher power mode and the first sensing element is operated in a lower power mode.
