描述
Grove – Dust Sensor(PPD42NS)Shinyei 日本神榮 PM 2.5 細懸浮微粒感測器模組
PPD42NS 灰塵傳感器通過測量灰塵濃度,可以很好地指示環境中的空氣質量。空氣中的顆粒物水平(PM水平)通過以給定的時間單位計算低脈衝佔用時間(LPO時間)來測量。LPO時間與PM濃度成正比。該傳感器可以為空氣淨化器系統提供可靠的數據; 它對直徑1μm的PM有反應。
注意: 該傳感器採用計數法測量粉塵濃度,不採用稱量方式,單位為pcs / L或pcs / 0.01cf。

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.
