Abstract
A carbon monoxide (CO) detection unit incorporates a sensor which is a film or layer of NixCo1−xOy where x is from 0.1 to 0.9, e.g., spinel. The CO is detected by measuring the change in the electrical properties of the sensor. The detector can measure CO concentrations below 100 ppm and is capable of operating at room temperature and can be applied to domestic, industrial, medical and vehicular use.
Claims40
A method for detecting carbon monoxide in air comprising contacting the air with a sensor element which incorporates a composition formed from NixCo1−xOy, where x is from 0.1 to 0.9 and y is 4x;
- and monitoring one or more electrical properties of the sensor element.
A device for monitoring carbon monoxide levels in air, wherein the device includes a sensor element having a film or layer comprising NixCo1−xOy, where x is from 0.1 to 0.9 and y is 4x.
