The present paper describes the synthesis of gas sensors based on thin films perovskite-type over a / substrate with interdigitated Pt-electrodes using the drop coating method. The perovskite starting nanoparticles have been prepared by the sol-gel method and they have an orthorhombic structure with space group. The prepared thin film has been tested as a sensitive film for ozone detection and shows a promising response. The detection of low concentration of ozone (equal to ) makes the prepared thin film a potential sensor for ozone detection.
