Abstract: In the present work, an extensive experimental investigation of TiO2 film has been carried out. TiO2 films have been deposited on a prism base by using sol-gel spin process. As the humidity increases in the environment where such films are placed, physisorption and chemisorption of water take place through the pores of films. This leads to a corresponding modulation in the intensity of reflected light. Thus, relative humidity is estimated directly in terms of modulation in the intensity of light observed on a digital power meter. Surface morphology of TiO2 films has also been studied.
