Abstract: The present invention relates to a sensor for sensing hydrogen. The sensor of the present invention comprises: a core which reacts with hydrogen to change a resistance value; at least two electrodes connected to the core; and a variable resistor which is connected to at least one of the two electrodes and of which the resistance value changes in response to a control signal, wherein the core includes palladium having a thin film shape, and graphene which is applied on the palladium and has a thin film shape.
