ESP8266 NodeMcu Lua & PM2.5_PMS5003_G5 & LCD

//  1：紫色==>5V (V V)因為V V才是5V的電   2：橘色==>GND  4：藍色RX==>TX 5：綠色TX==>RX
// 本程式除了PM2.5 G5外，在多接上一個2*16的LCD當作顯示
// LCD接腳 GND==>GND VCC==>5V SDA==>D2 SCL==>D1

// 利用以上程式可以得到PM1.0、PM2.5、PM10分別在CF=1為標準顆粒物、atmosphere為大氣環境下
// CF=1 根據美國TSI公司的儀器校準
// 大氣環境下 根據中國氣象局的數據校準
#include <LiquidCrystal_I2C.h>  //加入LCD函數庫
#include <Wire.h>
#include <ESP8266HTTPClient.h>
