Multiple ZnO nanorod device detecting $NO_2$ gas was fabricated by sol-gel growth method and gas response characteristics were measured as a chemical gas sensor. The device is mainly composed of sensing electrode and sensing nano material. To acquire high sensitivity of the device for $NO_2$ gas it was heated by a heat chuck up to $400^{\circ}C$ The sensing part was easily made using the CMOS compatible process, for example, the large area and low temperature nano material growth process, etc. The sensors were successfully demonstrated and showed high sensitive response for $NO_2$ gas sensing.
