<p>An odour sensor utilises an amine or an aldehyde dispersed in a polymer film to detect a vapour phase aldehyde or amine respectively. The amine and aldehyde react to form fluorescent reaction product which is detected by measuring the fluorescence emitted after irradiating the sensor element with UV light. The sensor contains a camera and a programmed cpu to analyse the fluorescence to determine the identity of the vapour phase molecule and its concentration.</p> |
