По това време технологията беше доста ограничена, а решението, използвано за количествено определяне на замърсяването на въздуха, беше сложно и наистина скъпо.</p> <div style='float:right;max-width: 50%; width:300px;color:#888;font-size: 66%;text-align: center;'> <img style='width:100%' src='/images/sensors/US7947503-Monitor-and-methods-for-characterizing-airborne-particulates.png'> Patent <a href='https://www.google.com/patents/US7947503'>US7947503</a>: Monitor and methods for characterizing airborne particulates </div> <p>За щастие в наши дни, с най-новите и модерни технологии, решенията, използвани за мониторинг на качеството на въздуха, стават не само по-прецизни, но и по-бързи при измерване. Устройствата стават все по-малки и струват много по-достъпни от всякога. Например, новите технологии като <i>осцилиращия микробаланс със заострен елемент</i> ( <a href='https://www.qld.gov.au/environment/pollution/monitoring/air-pollution/oscillating-microbalance/'>TOEM</a> ) осигуряват значителни предимства пред традиционните <i>монитори за бета затихване</i> ( <a href='https://www3.epa.gov/ttnamti1/files/2009conference/Hart.pdf'>BAM</a> ).</p> <p>Още по-наскоро ултрадостъпни сензори започват да се появяват на пазара - много от тях са свързани с <a href='https://en.wikipedia.org/wiki/Internet_of_things'>IOT</a> тенденцията да се усеща всичко. Въпреки че повечето от тях са чисто трик и определено безполезни играчки, някои от тях започват да постигат производителност, сравнима с професионалните монитори, при сто пъти по-ниска цена за тях. За да се оцени надеждността на тези сензори, <a>Earth Sensing Labs</a> от проекта World Air Quality Index провеждат и провеждат много изследвания със сензори за качество на въздуха и експерименти с данни на живо от много години.</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>Сензори за частици</p></h2><section> <p>Сензорите за частици могат да открият количеството прах във въздуха.
