夏普SHARP灰尘颗粒传感器GP2Y1010AU0F

Dust Sensor灰尘传感器用户手册1.特性和原理本模块是以夏普GP2Y1010AU0F为核心的灰尘传感器。

传感器内部的红外二极管，可以输出一个跟灰尘浓度成线性关系的电压值。

通过该电压值即可计算出空气中的灰尘和烟尘含量。

测量对象：直径大于0.8μm灰尘颗粒有效量程：500μg/m3输出类型：电压模拟量工作电压： 2.5V~5.5V产品尺寸：63.2mm×41.3mm固定孔尺寸： 2.0mm通气孔尺寸：9.0mm1.1.传感器输出特性传感器输出电压与灰尘浓度关系在0到0.5mg/m3范围内成线性关系，如下图所示：图1: 传感器输出特性曲线1.2.传感器控制原理1)通过设置模块I LED引脚为高电平，从而打开传感器内部红外二极管。

2)等待0.28ms，外部控制器采样模块A OUT引脚的电压值。

这是因为传感器内部红外二极管在开启之后0.28ms，输出波形才达到稳定。

如下图所示：图2: I LED与红外二极管输出波形关系3)采样持续0.04ms之后，再设置I LED引脚为低电平，从而关闭内部红外二极管。

4)根据电压与浓度关系即可计算出当前空气中的灰尘浓度，具体实现细节请参考Demo程序。

注：输出的电压经过了分压处理（查看原理图），要将测得的电源放大11倍才是实际传感器输出的电压。

夏普灰尘传感器原理夏普灰尘传感器是一种常用于空气质量监测的传感器，可以通过测量空气中的灰尘浓度，判断空气的污染程度。

它是基于光学原理工作的，通过测量光的散射来间接测量空气中的灰尘颗粒数量。

夏普灰尘传感器的原理是利用散射光的特性来测量灰尘浓度。

当光线照射到灰尘粒子上时，由于灰尘粒子的形状和大小不同，光线会发生不同程度的散射。

传感器中的激光二极管发射出一束单色激光，该激光经过准直透镜和散射板，形成一束平行光。

当光线遇到空气中的灰尘粒子时，部分光线会被散射到散射板上的光敏电阻。

散射到散射板上的光线，会被光敏电阻转化为电信号。

夏普灰尘传感器采用了光敏电阻的电阻值与光强成反比的原理。

当光敏电阻接收到较少的光线时，电阻值较高，电流较小；当光敏电阻接收到较多的光线时，电阻值较低，电流较大。

通过测量光敏电阻的电流大小，就可以得到空气中灰尘的浓度。

为了避免其他因素干扰，夏普灰尘传感器采用了光路双光子法。

传感器中设置两个光敏二极管，其中一个光敏二极管用来检测散射光的强度，另一个光敏二极管用来检测透射光的强度。

透射光是指光线通过空气中没有灰尘的部分，达到另一侧光敏二极管上。

通过对比散射光和透射光的强度差异，可以消除其他因素对灰尘浓度测量的影响，提高测量的准确性。

夏普灰尘传感器还通过在光路中加入一个专用滤光片来选择测量特定粒径的灰尘颗粒。

这个滤光片只允许特定波长的光线通过，其他波长的光线则会被滤除。

通过选择适当的滤光片，可以使传感器只测量某一特定粒径的灰尘颗粒，排除其他尺寸颗粒的干扰。

综上所述，夏普灰尘传感器是通过测量光线的散射来间接测量空气中的灰尘浓度。

传感器采用了散射光和透射光之间的差异，以及滤光片的选择，来消除其他因素对测量结果的影响。

这种原理使得夏普灰尘传感器在空气质量监测领域具有较高的准确性和可靠性。

pm2.5传感器四种工作原理及进口品牌介绍工采网小编从原理出发介绍当下pm2.5传感器应用普遍,进口品牌较多的综合评测、方便集成采用选型原理介绍：1,光散射法光散射原理有LED光（普通光学），激光等原理，传感器可以有效的探测出粒径约0.5um 以上颗粒，至此光散射法听着可靠性相对较低，然而又由于光散射原理探头相对便宜，探头易安装，使用，做为监测应用相对合适，相对其它原理有较多的优势，且应用商选择质量较好，并相对稳定，灵敏的探头，数据可靠性大大增加！目前市面上光散射法应用成熟普遍，是pm2.5监测的较好选择！2、重量法我国目前对大气颗粒物的测定主要采用重量法。

其原理是分别通过一定切割特征的采样器，以恒速抽取定量体积空气，使环境空气中的PM2.5和PM10被截留在已知质量的滤膜上，根据采样前后滤膜的质量差和采样体积，计算出PM2.5和PM10的浓度。

必须注意的是，计量颗粒物的单位ug/m3 中分母的体积应该是标准状况下（0℃、101.3kPa）的体积，对实测温度、压力下的体积均应换算成标准状况下的体积。

环境空气监测中采样环境及采样频率要按照HJ.T194的要求执行。

PM10连续自动监测仪的采样切割装置一般设计成旋风式，它在规定的流量下，对空气中10um粒径的颗粒物具有50%的采集效率、以下为其技术性能指标表。

3、微量振荡天平法TEOM微量振荡天平法是在质量传感器内使用一个振荡空心锥形管，在其振荡端安装可更换的滤膜，振荡频率取决于锥形管特征和其质量。

当采样气流通过滤膜，其中的颗粒物沉积在滤膜上，滤膜的质量变化导致振荡频率的变化，通过振荡频率变化计算出沉积在滤膜上颗粒物的质量，再根据流量、现场环境温度和气压计算出该时段颗粒物标志的质量浓度。

微量振荡天平法颗粒物监测仪由PM10采样头、PM2.5切割器、滤膜动态测量系统、采样泵和仪器主机组成。

流量为1m3/h环境空气样品经过PM10采样头和PM2.5切割器后，成为符合技术要求的颗粒物样品气体。
