作品1 2.0 添加短信通知功能

之前做了一个利用LCD屏监视植物土壤湿度和周围环境温度和湿度的小作品，昨晚修改了一下添加了当泥土湿度过高或者过低的时候Arduino会发信息到预设好的手机提醒状况。基本上都是上次的配件，加上DFRobot的TEL0051模块。

PS：不知道是其他问题，还是IDE的问题，还是GSM模块的问题发不了还有中文字的信息，希望前辈可以帮忙看看有没有办法修改一下。

代码如下：

//sensor pin A0, SCL AREF-2, SDA AREF-1; Sensor 3V, LCD 5V
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#include <dht11.h>
#define DHT11PIN A1
dht11 DHT11;
LiquidCrystal_I2C lcd(0x27, 24,3);
int sensorPin = A2;    // select the input pin for the potentiometer
int sensorValue = 0;  // variable to store the value coming from the sensor
int counter=0;
int sentSMSCounter=0;
String num="AT+CMGS="***********"";
void setup() {
  // declare the ledPin as an OUTPUT:
   //Serial.begin(9600);  
   //--------------------------------------
    //端口模式设置
    pinMode(3,OUTPUT);
    pinMode(4,OUTPUT);
    pinMode(5,OUTPUT);
    //GSM开机时序
    digitalWrite(5,HIGH);
    delay(1500);
    digitalWrite(5,LOW);  

    //使能GSM串口
    digitalWrite(3,LOW);
    digitalWrite(4,HIGH);
    delay(2000);
    //设置波特率
    Serial.begin(9600);
    //等待call ready
    delay(5000);
    delay(5000);
    delay(5000);
   //--------------------------------------
