In the present paper, we reported the sensing behavior and mechanism of a titanium dioxide-based thick film sensor for the detection of propanol at room temperature. Undoped titanium dioxide (UTO) and 2 wt% cadmium sulfide doped titanium dioxide (CdTO) thick film samples are fabricated on an alumina substrate. The response of the fabricated samples is measured with varying concentrations of propanol (0–5000 ppm) in a testing chamber at room temperature. The measurement showed that the 2 wt% CdS doped sample showed a maximum response (63 %) for propanol. The transient response is also measured and the response time is 65 s and recovery 195 s.
