$SnO_2$ as raw material of sensor for $NO_2$ detection was prepared by precipitating $SnCl_4$ solution with aqueous ammonia followed by calcining in air. The characterization of $SnO_2$ was carried out using FT-IR and XRD, and $SnO_2$ thick film sensor was fabricated by screen-printing method. The particle size of $SnO_2$ calcined at higher temperature increased due to the growth of crystalline. $SnO_2$ sensor fabricated by using $SnO_2$ sample calcined at $1000^{\circ}C$ followed by heat treatment at $700^{\circ}C$ exhibited excellent sensing characteristics and selectivity for $NO_2$ gas at the operating temperature of $250^{\circ}C$.
