<P>We introduce a simple method to fabricate an ammonia gas sensor with a nanocomposite of single-walled carbon nanotubes (SWNTs) and SnO<SUB>2</SUB>. The nanocomposite showed a semiconducting property. With exposure to ammonia gas, the electrical resistance of the nanocomposite sensor increases rapidly. It was found that the sensor can detect the concentration of NH<SUB>3</SUB> down to the 10 ppm level at room temperature. The sensor exhibited a fast response time of less than 100 s and good sensing response and recovery. (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)</P>
