The system uses individual glass chambers and a 0.4 L\/min air pump to recirculate the gases towards the sensors.<\/li>\n<li data-path-to-node=\"9,1,0\">Temperature modulation: Unlike static sensors, this device applies sinusoidal voltage cycles (from 1.6 V to 5 V) to the sensor heaters. This generates dynamic responses that significantly increase the ability to discriminate between different odours.<\/li>\n<li data-path-to-node=\"9,2,0\">Analysis software: Includes a MATLAB interface for data acquisition, processing and classification using algorithms that compare the sample with reference patterns.<\/li>\n<\/ul>\n<\/div>\n<\/section>\n<p><!-- APPLICATIONS --><\/p>\n<section style=\"margin-bottom: 2rem\">\n<h3 style=\"background-color: #a6192e;color: #fff;padding: 0.5rem 1rem;border-radius: 4px 4px 0 0;font-size: 1.1rem\">TECHNOLOGY APPLICATIONS<\/h3>\n<div style=\"border-left: 4px solid #B6A19E;padding-left: 1rem;background-color: #f9f9f9;padding: 1rem\">\n<p data-path-to-node=\"17\">The electronic nose is a strategic asset for:<\/p>\n<ul>\n<li data-path-to-node=\"18,0,0\">Fruit and Vegetable Packing Facilities: Automating fruit sorting according to ripeness for different markets (domestic versus export).<\/li>\n<li data-path-to-node=\"18,1,0\">Logistics and Transport Companies: Monitoring cargo in shipping containers to detect the early stages of rotting.<\/li>\n<li data-path-to-node=\"18,2,0\">Agricultural Analysis Laboratories: A rapid screening tool before proceeding to more costly chemical analyses.<\/li>\n<\/ul>\n<\/div>\n<\/section>\n<p><!-- ADVANTAGES AND INNOVATIVE ASPECTS --><\/p>\n<section style=\"margin-bottom: 2rem\">\n<h3 style=\"background-color: #a6192e;color: #fff;padding: 0.5rem 1rem;border-radius: 4px 4px 0 0;font-size: 1.1rem\">ADVANTAGES AND INNOVATIVE ASPECTS<\/h3>\n<div style=\"border-left: 4px solid #B6A19E;padding-left: 1rem;background-color: #f9f9f9;padding: 1rem\">\n<ul>\n<li>Technological advantages (rapid, immediate diagnosis) and economic advantages (the cost of the technology developed is lower than that of competing technologies) for companies and organisations in the agri-food sector.
