The PANi-SnO{sub 2} hybrid nanocomposite based thin films doped with 10–50 wt % CSA were deposited on the glass substrates using the spin coating technique. The sensor response in relation to the CSA doping concentration and the gas concentration has been systematically studied. A significant sensitivity (91%) towards 100 ppm NH{sub 3} operating at room temperature is observed for the 30 wt % CSA doped PANi-SnO2 nanohybrid. The sensing mechanism of CSA doped PANi-SnO{sub 2} materials to NH{sub 3} was presumed to be the effect of p–n heterojunctions.
