CO SENSOR AND METHOD OF FABRICATING THE SAME

摘要

PURPOSE: CO sensor and method of fabricating the same is provided to prevent that the CO sensor resistance increase as a time and to increase the dependence of CO concentration of CO sensor resistance. CONSTITUTION: In the CO sensor, CO sensor using SnO2 group oxide semiconductor is agglomerated, Ir and Pt is added with weight rate 1-1/5. a mixing solution of Ir and Pt is impregnated and dissolve through pyrolysis, and added. An aqueous solution containing a thio component is impregnated in SnO2 sinter. The thio component is added in the SnO2 sinter. Temperature-humidity dependency of the CO sensor is controlled, and dependency of the CO concentration is increased.
