That reading is what appears on the LCD display module and what drives automatic mode, so the unit speeds up when the air is dirty and settles down when it is clean. A sensor that has clogged with dust or failed will leave the unit stuck on one speed or showing a reading that never changes — that is when it is worth replacing.\u003c\/p\u003e\u003ch3\u003eFits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eV.E.M. \/ Nanyoo NYDZ-QR-600G fresh air unit\u003c\/li\u003e\n\u003cli\u003eV.E.M. \/ Nanyoo NYDZ-QR-1200G fresh air unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: VEM-NY-LASER\u003c\/li\u003e\n\u003cli\u003eType: laser particle sensor (PM2.5)\u003c\/li\u003e\n\u003cli\u003eFunction: feeds the air quality reading and automatic fan speed\u003c\/li\u003e\n\u003cli\u003eSold as: one sensor\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIn stock in Zahle, delivered across Lebanon.\u003c\/p\u003e","brand":"V.E.M.","offers":[{"title":"Default Title","offer_id":54479509356862,"sku":"VEM-NY-LASER","price":31.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/4952\/3518\/files\/VEM-NY-LASER_2f71c91c-194c-4e1e-910a-954638557cac.png?v=1789814155","url":"https:\/\/azargroup.org\/products\/vem-laser-sensor-for-air-purifier","provider":"Azar Group","version":"1.0","type":"link"}
