Concept, design and sensible implementation of a miniaturized spectrophotometer, utilized as a mid-infrared-based multi gasoline sensor is described. The sensor covers an infrared absorption wavelength vary of two.9 to 4.eight um, offering detection capabilities for carbon dioxide, carbon monoxide, nitrous oxide, sulphur dioxide, ammonia and methane. A lead selenide photo-detector array and customised MEMS-based micro-hotplate… Continue reading
