SnO2 ndi yofunika semiconductor sensa zakuthupi ndi lonse gulu kusiyana, amene ndi Mwachitsanzo = 3.6 eV kutentha firiji.Chifukwa ma nanomatadium ali ndi mawonekedwe a tinthu tating'onoting'ono komanso malo akulu enieni, mawonekedwe amagetsi azinthuzo amatha kusintha kwambiri.Sensa ya gasi yokonzedwa nayo imakhala ndi chidwi chachikulu ndipo imagwiritsidwa ntchito kwambiri pozindikira komanso kulosera zamitundu yosiyanasiyana yoyaka moto, mpweya woyipitsidwa ndi chilengedwe, mpweya wotayira m'mafakitale ndi mpweya woipa, monga CO, H2S, NOx, H2, CH4, ndi zina zambiri.
Sensa ya chinyezi yokonzedwa ndi SnO2 monga maziko ake ali ndi ntchito pakuwongolera malo amkati, zipinda za zida zolondola, malaibulale, malo owonetsera zojambulajambula, malo osungiramo zinthu zakale ndi zina zotero.Pogwiritsa ntchito doping-quantitative Co0, Co2O3, Cr2O3, Nb2O5, Ta2O5, ndi zina zotero mu SnO2, ma varistors okhala ndi makhalidwe osiyanasiyana okana amatha kupangidwa, omwe amagwiritsidwa ntchito kwambiri pamagetsi, mabwalo amagetsi, ndi zipangizo zapakhomo.
