夏普GP2Y1010AU0F_粉塵傳感器參考程序

1、夏普GP2Y1010AU0F粉塵傳感器參考程序簡介：Sharps GP2 Y1010AU0F是一款光學空氣質(zhì)量傳感器，設計用來感應空氣中的塵埃粒子，其內(nèi)部對角安放著紅外線發(fā)光二極管和光電晶體 管，使得其能夠探測到空氣中塵埃反射光，即使非常細小的如煙草煙霧 顆粒也能夠被檢測到，通常在空氣凈化系統(tǒng)中應用。該傳感器具有非常低的電流消耗（最大20mA典型值11mA ,可使用高達7VDC該傳感器輸出為模擬電壓，其值與粉塵濃度成正比?？蓽y量0.8微米以上的微笑粒子，感知煙草產(chǎn)生的咽氣和花粉，房屋粉塵 等.體積小,重量輕,便于安裝，廣泛應用于空氣清新機，換氣空調(diào)，換氣 扇等產(chǎn)品.靈敏度：30.5V/0.1m
