ZnO/CuO hetrostructure was successfully deposited on glass substrate by using simple catalyst free thermal evaporation technique followed by annealing at different atmosphere. The surface morphology of hetrostructure film was analyzed by scanning electron microscopy (SEM). The gas sensing outcome established the hetrostructure sensors are highly responds towards toxic NO2 gas as compare to other analyte gases. The hetrostructure sensor exhibits a maximum response of 175 % to NO2 gas with very squat response / recovery time and outstanding reproducibility and stability also. Furthermore, the hetrostructure sensor responds to an enormously minute exposure of NO2 gas i.e. 1 ppm. The interaction of hetrostructure sensor with NO2 gas has effectively measured by employing an impedance spectroscopy measurement.
