Abstract	Tin oxide (SnO2) gas sensor has been fabricated on glass substrate by using thermal evaporation and further characterize by scanning electron microscopy, atomic force microscopy and EDAX analysis for confirming its morphology and composition. The chemiresistive gas sensing performance of SnO2 films were studied towards various oxidizing and reducing gases. The experimental results reveal that, SnO2 films were vastly sensitive and selective towards NO2 gas than other test gases. SnO2 sensor exhibit maximum response of 160 % for 100 ppm NO2 gas with very fast response time at optimal operating 200 °C temperature. The SnO2 sensor manifests remarkably enhanced sensing performance, including fast response and recovery time, high sensitivity, and good stability, suggests of the promising application in the NO2 gas sensing field.
