Abstract
A multiple sensor array for breath acetone measurement has a semiconductor sensor that measures concentration of a set of volatile organic compounds. An electrochemical sensor measures volatile organic compounds or other gasses such as carbon monoxide. At least one correction sensor that measures other breath properties can also form a part of the multiple sensor array, providing information on physical properties such as pressure and temperature, and information related to individual gases including carbon monoxide, water vapor, hydrogen, ethylene oxide, and the like. An acetone concentration calculation module takes measured values from the multiple sensor array to measure breath acetone, which can be stored and displayed for a user.
