In the present work SnO2 nano-powder has been synthesized by a sol–gel method. Thick film pastes are then developed by using as-synthesized SnO2 nano-powder with two different concentrations (0.5 and 1 wt %) of palladium (Pd). After that, the thick film sensor has been fabricated for the detection of various concentrations (1–5 vol %) of Liquefied Petroleum Gas (LPG). The investigations depict that sensing response of Pd-doped SnO2 is size dependent and small particles are found to be enhance the sensitivity of the sensor. The mechanism for LPG sensing has been also described.
