    We have demonstrated multi-walled carbon nanotube (MWCNTs) based sensors, which are capable of detecting alcohol vapor. The properties of the sensor were as a function of baking times at ethanol flow rate 200 cc/min and nitrogen gas flow rate 200 cc/min. Moreover, the various of baking times were observed that the highest sensitivity was obtained at baking time of 25 minutes at 70 ° C can be explained for residual of ethanol on the surface .It was found that the optimum operating at room temperature (25 °C). It is expected that many applications of CNTs-based sensors will be explored in future as the interest of the nanotechnology research in this field increases.
