Abstract

A high-sensitivity carbon monoxide sensor is shown and described. The sensor includes a sensing element (12) having a catalyst dispersed over a metal oxide layer (15) . The catalyst is capable of adsorbing carbon monoxide. The sensing element can also include a heater (16) and a temperature sensor (14) . A flow sensor (18) is provided for sensing a flow rate of gas directed at the sensing element. The signal processing module (22) is coupled to the flow sensor (18) and the temperature sensor (14). A flow sensor sends signals indicative of the flow rate to the processing module while the temperature sensor sends signals indicative of the temperature of the sensing element to the processing module. After carbon monoxide has been adsorbed onto the catalyst and metal oxide layer for a fixed time period, the heater is activated to heat the sensing element above the light-off temperature or at least as high as the oxidation temperature of the adsorbed carbon monoxide. As a result, an exothermic oxidation of the adsorbed carbon monoxide takes place, which results in an increase in the temperature of the sensing element. This increase in the temperature of the sensing element is used to determine the amount of accumulated adsorbed carbon monoxide which, in conjunction with the flow rate and the fixed time period, is used to calculate the carbon monoxide concentration in the gas flow.
