Title:
ADSORPTION BASED CARBON MONOXIDE SENSOR AND METHOD
Document Type and Number:
WIPO Patent Application WO2002044702
Kind Code:
A3
Abstract:
A carbon monoxide sensor and method is shown and described. The sensor includes a sensing element that includes an adsorbent dispersed over a support material. The adsorbent is capable of exothermically adsorbing carbon monoxide. The sensor also includes a temperature sensor in contact with the sensing element and a signal processing module coupled to the temperature to the temperature sensor. The temperature sensor communicates signals indicative of a temperature increase of the sensing element to the processing module, thereby indicating an adsorption and, therefore, a presence of carbon monoxide.
