This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration. The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in 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.
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting StartedandIntroduction to Grove before your using of the product.
Note
This sensor uses counting method to measure dust concentration, not weighing method, and the unit is pcs/L or pcs/0.01cf.
Please pay attention to the warnings listed here.

這種灰塵感應器通過測量粉塵濃度, 在環境中提供了良好的空氣品質指標。通過計算給定時間單位內的低脈衝佔用時間 (LPO 時間) 來測量空氣中顆粒物水準 (PM 水準)。LPO 時間與 PM 濃度成正比。該感應器可為空氣淨化系統提供可靠的資料;它對直徑1的 PM 回應。
對於所有格羅夫使用者 (特別是初學者), 我們為您提供指導 PDF 文檔。請在使用該產品之前下載並閱讀序言-入門版和介紹到格羅夫。
注意
該感應器採用計數法測量粉塵濃度, 而不是稱量法, 單位為 pc/L 或0.01cf。
請注意列出的警告此處.
