A new type of hydrogen sensor based on optical fiber extrinsic Fabry-Perot interferometric with palladium film is proposed. When exposed to hydrogen, the palladium absorbs hydrogen and produces a change in the gap length of the sensor. The stress transfer model of the sensor is analyzed and the relationship between the change of Fabry-Perot gap length and hydrogen concentration is constructed. The response of the sensor to hydrogen is measured. The analytical value is close to the experimental result.
