The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in a given time unit. LPO time is proportional to PM concentration. This sensor can provide reliable data for air purifier systems; it is responsive to PM of diameter 1μm.\u003cbr\u003e\n\u003cbr\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp style=\"text-align: justify;\"\u003eThis sensor uses a counting method to measure dust concentration, not weighing method, and the unit is pcs\/L or pcs\/0.01cf.\u003cbr\u003e\nPlease pay attention to the warnings listed here.\u003c\/p\u003e\n\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli style=\"text-align: justify;\"\u003eGrove compatible interface(extra wire with connector)\u003c\/li\u003e\n\t\u003cli style=\"text-align: justify;\"\u003eSupply voltage range: 5V\u003c\/li\u003e\n\t\u003cli style=\"text-align: justify;\"\u003eMinimum detect particle: 1um\u003c\/li\u003e\n\t\u003cli style=\"text-align: justify;\"\u003ePWM output\u003c\/li\u003e\n\t\u003cli style=\"text-align: justify;\"\u003eDimensions: 59(W)x45(H)x22(D) [mm]\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eApplication Ideas:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli style=\"text-align: justify;\"\u003eAir Purifier\u003c\/li\u003e\n\t\u003cli style=\"text-align: justify;\"\u003eAir Quality Monitor\u003c\/li\u003e\n\t\u003cli style=\"text-align: justify;\"\u003eAir Conditioner\u003c\/li\u003e\n\t\u003cli style=\"text-align: justify;\"\u003eVentilator\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Grove (Seeed Studio)","offers":[{"title":"Default Title","offer_id":52449954660684,"sku":"TPX00056","price":11.5,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0529\/4191\/4282\/files\/TPX00056_03.front.jpg?v=1774608985","url":"https:\/\/store.oniudra.cc\/products\/grove-dust-sensor-ppd42ns","provider":"EU Test Store","version":"1.0","type":"link"}
