【关键词】PM2.5；灰尘传感器；单片机；A/D转换1.引言PM2.5是指大气中直径小于或等于2.5微米的颗粒物，也称为可入肺颗粒物。

PM2.5粒径小，富含大量的有毒、有害物质且在大气中的停留时间长、输送距离远，因而对人体健康和大气环境质量的影响很大。

据有关部门统计调查显示，2012年北京、上海因PM2.5污染分别造成早死人数为2349、2980人，分别占当年死亡总人数的比例为1.9%、1.6%，经济损失分别为18.6、23.7亿元。

而2012年北京、上海因交通意外死亡人数分别为974人和1009人。

可见，PM2.5对人类的危害极大。

PM2.5粉尘颗粒的即时检测，是有效防治PM2.5污染的前提和重要保障。

为此，本文介绍了PM2.5粉尘颗粒检测仪的研制方法，主要包括设计原理、结构组成、技术指标等。

PM2.5粉尘颗粒检测仪可用于：室内、汽车内空调排风口粉尘浓度检测；环保监测部门大气飘尘检测，污染源调查；建筑或爆破等生产现场粉尘浓度的测定；精密仪器等高清洁生产环境的空气检测等。

2.PM2.5粉尘颗粒检测仪的设计原理PM2.5粉尘颗粒检测仪设计原理如下：灰尘传感器实时的检测空气中直径小于或等于2.5微米的颗粒物的含量，并根据含量比例输出模拟电压信号，该信号经过A/D转换后，由单片机进行采集、计算、数据处理后，在LED显示屏上，显示出PM2.5的数值。

当PM2.5超过仪器设定值时，产生声光报警，并存储当前PM2.5值和时间参数等。

3.PM2.5粉尘颗粒检测仪的结构组成PM2.5粉尘颗粒检测仪（如图1）由单片机、灰尘传感器单元、用户输入单元、A/D转换单元、LED显示屏、电源单元、监控复位单元、时钟单元和报警单元等九部分构成。

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。

空气粉尘浓度检测器电路设计与软件编程论文空气粉尘浓度检测器电路设计与软件编程论文本设计以ATmega382p单片机为控制中心，由GP2Y1010AU0F 光学空气质量传感器测量空气粉尘浓度，通过单片机内置的10位A/D 转换将模拟的电压信号转换成数字信号，得到粉尘浓度值，并由LCD1602显示屏显示出来。

0 引言随着人类工业和经济的快速发展，我们的环境污染越来越严重。

除废气、废水外，颗粒状粉尘、烟尘向大气排放所造成的污染已成为一个十分突出的问题。

PM2.5，PM10，PM0.1及其吸附的重金属粒子是雾霾的重要组成部分[1]。

2012年2月，《环境空气质量标准》新增了对PM2.5的检测指标，PM2.5成为空气质量标准之一。

数据表明，我国空气质量超标的城市中68%都存在可吸入颗粒物的问题[2]。

由此可以看出粉尘对人类健康和生产的危害十分严重。

所以，粉尘浓度的检测和控制具有重要的意义。

1 系统工作原理单片机选用ATmega328p，粉尘浓度传感器选用夏普GP2Y1010AU0F灰尘传感器，按键部分通过电阻与按键串联将信号输入模拟口，通过读取模拟值的不同判断按键值，显示部分采用LCD1602并用采取I2C总线的8位远程I/O扩展口芯片PCF8574进行引脚简化。

将粉尘检测器电源开关打开，当传感器得到一个由粉尘浓度转换得来的0～5V的`电压信号时，进入单片机，经过处理后转变为十进制数通过I/O口在显示屏上显示出精确数值。

数值量随输入电压的扰动而变化。

同时键盘设定预警值送入单片机，与测量值一同显示出来。

当采集的当前粉尘浓度大于预警值时，单片机驱动蜂鸣器报警。

2 系统电路设计2.1 电路总体设计以ATmega328p单片机为核心，主要包括单片机处理模块，信号采集模块，独立按键模块，显示模块和蜂鸣器报警模块。

系统通过信号采集模块采集空气中的粉尘，得到0～5V的电压信号后，由单片机内部自带的10位ADC进行模数转换得到粉尘浓度，与此同时，通过独立按键模块设定浓度预警值，通过液晶显示模块将粉尘浓度和预警值同时显示在显示屏上。

使用夏普GP2Y1010AU0F灰尘传感器检测空气质量夏普灰尘传感器价格较便宜，能检测出室内空气中的灰尘和烟尘含量.检测原理其原理如下图，传感器中心有个洞可以让空气自由流过，定向发射LED光，通过检测经过空气中灰尘折射过后的光线来判断灰尘的含量。

电路图因为数据是通过pin 5的电压模拟信号输出的，而树莓派的引脚不支持模拟信号直接读取（需要增加数模转换芯片），所以先用Arduino来实验。

Arduino 代码根据电路图，把Arduino和传感器连接起来：1.Sharp pin 1 (V-LED) => 5V 串联1个150欧姆的电阻（最好在电阻一侧和GND之间再串联一个220uf的电容）2.Sharp pin 2 (LED-GND) => GND3.Sharp pin 3 (LED) => Arduino PIN 2 （开关LED）4.Sharp pin 4 (S-GND) => GND5.Sharp pin 5 (Vo) => Arduino A0 pin （空气质量数据通过电压模拟信号输出）6.Sharp pin 6 (Vcc) => 5V1./*2.Interface to Sharp GP2Y1010AU0F Particle Sensor3.Program by Christopher Nafis4.Written April 20125.6.7.8.9.Sharp pin 1 (V-LED) => 5V (connected to 150ohm resister)10.Sharp pin 2 (LED-GND) => Arduino GND pin11.Sharp pin 3 (LED) => Arduino pin 212.Sharp pin 4 (S-GND) => Arduino GND pin13.Sharp pin 5 (Vo) => Arduino A0 pin14.Sharp pin 6 (Vcc) => 5V15.*/16.#include<SPI.h>17.#include<stdlib.h>18.19.int dustPin=0;20.int ledPower=2;21.int delayTime=280;22.int delayTime2=40;23.float offTime=9680;24.25.int dustVal=0;26.int i=0;27.float ppm=0;28.char s[32];29.float voltage=0;30.float dustdensity=0;31.float ppmpercf=0;32.33.void setup(){34.Serial.begin(9600);35. pinMode(ledPower,OUTPUT);36.37.// give the ethernet module time to boot up:38. delay(1000);39.40. i=0;41. ppm=0;42.}43.44.void loop(){45. i=i+1;46. digitalWrite(ledPower,LOW);// power on the LED47. delayMicroseconds(delayTime);48. dustVal=analogRead(dustPin);// read the dust value49. ppm=ppm+dustVal;50. delayMicroseconds(delayTime2);51. digitalWrite(ledPower,HIGH);// turn the LED off52. delayMicroseconds(offTime);53.54. voltage=ppm/i*0.0049;55. dustdensity=0.17*voltage-0.1;56. ppmpercf=(voltage-0.0256)*120000;57.if(ppmpercf<0)58. ppmpercf=0;59.if(dustdensity<0)60. dustdensity=0;61.if(dustdensity>0.5)62. dustdensity=0.5;63.String dataString="";64. dataString+=dtostrf(voltage,9,4,s);65. dataString+=",";66. dataString+=dtostrf(dustdensity,5,2,s);67. dataString+=",";68. dataString+=dtostrf(ppmpercf,8,0,s);69. i=0;70. ppm=0;71.Serial.println(dataString);72. delay(1000);73.}把传感器和Ardiuno连接好后，可以连续打印出传感器的输出电压值。

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。

1.4 代码说明： 由于参考代码过多，在此对于常见的代码不予讲解，下面对于核心代码进行说明。 430 单片机特点：16 位处理器，低功耗，8M 的主系统时钟决定单指令周期为 0.125us，内 部集成众多外设，包括 12 位 ADC，定时器 A，定时器 B。强调一点是，由于此传感器要求 采样时序较为精确，因此像 430 这种中端的微处理器或者更高端的处理器比较适合开发此传 感器，也就是说指令的处理速度越快越好。 430 单片机带动传感器工作一次的时间大概为 1.5s，工作期间不间断提供输入脉冲，大概到 1s 左右，此时传感器的工作已经稳定，因此可以开始采样了，连续采样 4 次，然后将数据 取平均值，这就是一次工作的整个流程。这样的设计思路既可以保证传感器的读值稳定性， 又可以做到低功耗。 输入信号由定时器 A 产生，P1.2（TA1）输出，ADC 采样时序的控制由定时器 B 控制，使用 片内 12 位的 ADC 进行采样，采样的参考电压是系统电压 3.2V（做法比较粗糙），采样后直 接转成模拟信号的表达形式，最后输出的是电压值，对于电压转换到 PM2.5 的值，在 1.5 节 有简单说明。

夏普光学灰尘传感器（GP2Y1010AU0F）在检测非常细的颗粒，如香烟烟雾，是特别有效的，
并且是常用的空气净化器系统。

该装置中，一个红外发光二极管和光电晶体管，对角布置成允许其检测到在空气中的灰尘反射光。

该传感器具有极低的电流消耗（最大20mA，11毫安典型的），可以搭载高达7VDC的传感器。

输出的是一个模拟电压正比于所测得的粉尘浓度，敏感性为0.5V/0.1mg/m3。

检测原理
其原理如下图，传感器中心有个洞可以让空气自由流过，定向发射LED光，通过检测经过空气中灰尘折射过后的光线来判断灰尘的含量。
