Determination of toxic gases based on the responses of a single electrocatalytic sensor and pattern recognition techniques

Publication

- MEASUREMENT SCIENCE & TECHNOLOGY - Year 2014

A response from an electrocatalytic gas sensor contains fingerprint information about the type of gas and its concentration. As a result, a single gas sensor can be used for the determination of different gases. However, information about the type of gas and its concentration is hidden in the unique shape of the current–voltage response and it is quite difficult to explore. One of the ways to get precise information about the measured...
