We report oxygen sensing behavior of (Eu{sub 1-x}Ca{sub x})Ba{sub 2}Cu{sub 3}O{sub 7-{delta}}(x = 0.0,0.1) ceramics rods with formation of oxygen sensitive hot-spot upon application of external voltage. Oxygen response behavior of the x = 0.1 rod showed constant current plateau with increasing voltage and displayed better stability and reproducibility compared to x = 0 rod probably due to increased intrinsic hole concentration and reduction in activation energy as a result of Ca{sup 2+} substitution..
