Les appareils sont de plus en plus petits et coûtent beaucoup plus abordables que jamais. Par exemple, de nouvelles technologies telles que la <i>micro-balance oscillante à éléments coniques</i> (<a href='https://www.qld.gov.au/environment/pollution/monitoring/air-pollution/oscillating-microbalance/'>TOEM</a>) offrent des avantages significatifs par rapport aux <i>moniteurs d'atténuation bêta</i> traditionnels (<a href='https://www3.epa.gov/ttnamti1/files/2009conference/Hart.pdf'>BAM</a>)</p> <p>Plus récemment encore, des capteurs ultra-abordables commencent à apparaître sur le marché - beaucoup d'entre eux sont liés à la tendance <a href='https://en.wikipedia.org/wiki/Internet_of_things'>IOT</a> de détection. tout. Alors que la plupart d'entre eux ne sont que des gadgets, et donc des jouets définitivement inutiles, certains d'entre eux commencent à atteindre des performances comparables à celles des moniteurs professionnels, pour un coût cent fois inférieur. Afin d'évaluer la fiabilité de ces capteurs, les <a>Earth Sensing Labs</a> du projet World Air Quality Index mènent et mènent depuis de nombreuses années de nombreuses recherches sur les capteurs de qualité de l'air et des expériences avec des données réelles.</p> <style type='text/css'> section { margin-top:20px; margin-bottom: 80px; } @media only screen and (max-width: 800px) { border-top: 1px solid #ccc; } @media only screen and (min-width: 800px) { section { padding-left: 20px; border-left: 3px solid #f8f8f8; } } </style><h2><p>Capteurs de particules</p></h2><section> <p>Les capteurs de particules peuvent détecter la quantité de poussière dans l'air. Alors que la première génération était simplement capable de détecter le degré d'opacité, les capteurs les plus récents peuvent désormais détecter non pas les PM<sub>2,5</sub> et les PM<sub>10</sub>,

Sinon, d'un point de vue technologique, cela n'inclut rien de mieux que ce que les capteurs à 20 $ peuvent faire, sauf à partir d'un circuit intégré.</li> <li>Remarque 4 : Il existe de nombreux articles scientifiques sur les capteurs à faible coût.
