1、夏普GP2Y1010AU0F_粉尘传感器参考程序简介：Sharps GP2Y1010AU0F 是一款光学空气质量传感器，设计用来感应空气中的尘埃粒子，其内部对角安放着红外线发光二极管和光电晶体管，使得其能够探测到空气中尘埃反射光，即使非常细小的如烟草烟雾颗粒也能够被检测到，通常在空气净化系统中应用。该传感器具有非常低的电流消耗（最大20mA，典型值11mA），可使用高达7VDC。该传感器输出为模拟电压，其值与粉尘浓度成正比。可测量0.8微米以上的微笑粒子,感知烟草产生的咽气和花粉,房屋粉尘等.体积小,重量轻,便于安装，广泛应用于空气清新机,换气空调,换气扇等产品.灵敏度：0.5V/0.1mg/
