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

//设置波特率

//等待call ready
