Arduino 温度,湿度,PM检测
作者：阿圣(Sfan) 发布于：2013-4-26 13:20 Friday 分类：计算机
去年就在x宝上买了一套Arduino 的学习套件.一直没做什么东西.
北京的各种"霾",有了要做一个PM2.5检测小装置的想法.收集各种资料之后.X宝买各种工具和粉尘颗粒传感器.
基本结构: Arduino + enc28j60 + Dht11 + GP2Y1010AU0F + nokia 5110 lcd;
材料: 1.Arduino pro mini 2.ENC28j60以太网模块 3. sharp GP2Y1010AU0F 粉尘传感器 4.DHT11数字温/湿度传感器(这个便宜货精度太差) 5.Nokia 5110 液晶屏模块 6.过线塑料盒 7.各种工具杜帮线.
功能如下:
1.读取当前温度,湿度,可入肺颗粒数.并显示出来.
2.插上网线的话.根据网络环境自动获取IP或设置预设固定IP.并把读取的当前环境数据上传到 yeelink 平台
3.显示当前时间,日期(时间从网络UTC时间服务器读取)
4.可以自己定制相关功能.自己烧写程序
上几张图.
启动状态.右上角一个小图标是网络状态的.
温/湿度显示.
PM2.5 显示
上传到yeelink平台数据显示
Enc28j60 ,Arduino pro min ,nokia 5110
夏普 GP2Y1010AU0F
网络接口 和 电源的接口 电源 5V
粉尘传感器 [GP2Y1010AU0F] 外置 用热熔胶粘在后盖上,可当做整个盒子的支架
DHT11 温/湿度传感器 内嵌在盒子一侧 盒子顶端预留下载接口 (亲,别吐槽焊工 - -" ,电铬铁神马的都是刚买的有木有)

Serial.println(dustVal);
228
voltage = ppm/pm_i*0.0049;
229
dustdensity = 0.17*voltage-0.1;
230
ppmpercf = (voltage-0.0256)*120000;
231
if (ppmpercf < 0)
232
ppmpercf = 0;
233
if (dustdensity < 0 )
234
dustdensity = 0;
235
if (dustdensity > 0.5)
236
dustdensity = 0.5;
237
pm_i=0;
238
ppm=0;
239
pm2_5=dustdensity*1000;
240
Serial.print("voltage :");
241
Serial.println(voltage);
242
Serial.print("dustdensity :");
243
Serial.println(dustdensity);
244
Serial.print("ppmpercf :");
245
Serial.println(ppmpercf);
246
myGLCD.drawBitmap(0,15, cls, 84, 25);
247
myGLCD.update();
248
myGLCD.drawBitmap(8,15, pm2_5_ico, 30, 24);
249
myGLCD.setFont(BigNumbers);
250
myGLCD.printNumI(pm2_5,40,15);
251
myGLCD.update();
252
}
请问这个算法什么意思
