使用Arduino及乐联网平台搭建家居环境监测调节系统1.
功能实现：
实现了空气温湿度、PM2.5质量浓度的实时监测，本地显示、上传至乐联网，并可以直接自动控制空气净化系统工作，空气质量达标以后，又可以自动断电，节约能源；此外，利用乐联网平台实现了自动推送微博、短信预警、远程控制空气净化器的开关。
在此过程中，感谢张老师和乐联网刘先生的大力支持，没有两位的帮助，我这个非机电、非软件专业的业余人士不能实现这个系统的搭建。
P.S.乐联网的自动发送微博、短信功能真的非常便利，安卓APP也很棒~远程控制全靠他了。

2. 硬件列表：
（1） Arduino UNO 板子60左右，不过由于我是纯新手，买的是一个传感器套装，链接如下：
http://item.taobao.com/item.htm?spm=a1z09.5.0.42.eb1p7A&id=20149064414
（2）夏普GP2Y1010AU0F_粉尘传感器在新中发地下一层买的，好像45元吧。

（3） SHT10温湿度传感器购买地同上 40元。

（4） LCD12864 5V 蓝屏带背光中文字库 ST7920 提供驱动程序
淘宝购入，42元，链接如下：
http://item.taobao.com/item.htm?spm=a1z09.5.0.40.eDhp4p&id=10495880170

（5） Enc28j60 独立以太网控制器，远程控制的关键部，28元，新中发地下淘得。

（6）数据系统平台：乐联网http://www.lewei50.com
3. 硬件连接

（1）夏普GP2Y1010AU0F_粉尘传感器（按图示方式放置，从左到右分别为1~6脚）
Sharp pin 1 (V-LED) => 5V (串联150Ω电阻，pin 1和电阻之间连220μF电容接地);
Sharp pin 2 (LED-GND) => Arduino GND脚;
Sharp pin 3 (LED) => Arduino 数字口pin 2 ;
Sharp pin 4 (S-GND) => Arduino GND 脚;
Sharp pin 5 (Vo) => Arduino 模拟口A0pin;
Sharp pin 6 (Vcc) => 5V;
（2） SHT10
SHT10 pin s (时钟)=>Arduino 数字口 pin 9;
SHT10 pin d (数据) =>Arduino 数字口 pin 7;
SHT10 pin + => 5V;
SHT10 pin - => Arduino GND脚;
（3） LCD12864连接，使用了SPI接法，数据传输只需使用pin 3,9,8
pin1 = Arduino GND;
pin2 = 5V;
rs(CS) = Arduino pin 8;
rw(SID)= Arduino pin 9;
en(CLK) =Arduino pin 3;
psb = Arduino GND脚;
（4） ENC28J60模块的连接。
Vcc => Arduino Vcc;
Reset => Arduino Reset;
Enc-int =>Arduino 数字口pin 2;
GND => Arduino GND;
Sck => Arduino pin 13;
Miso => Arduino pin 12;
Mosi => Arduino pin 11;
Cs => Arduino pin 10.
