IOT watering plant with Adruino UNO and Wifi Shield


everyone knows what is " IOT " Interning Of thing. With now technology, we can do many thing that possible. I just want to share some programming that I make for my friend with simple programing using Adruino Uno and wifi shield.

#define BLYNK_PRINT Serial

#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>
#include <DHT.h>

char auth[] = "*****";
char ssid[] = "*****";
char pass[] = "*****"; //

#include <SoftwareSerial.h>
SoftwareSerial EspSerial(2, 3); // RX, TX

// Your ESP8266 baud rate:
#define ESP8266_BAUD 9600

ESP8266 wifi(&EspSerial);

//Constants
#define DHTPIN 7     // what pin we're connected to
#define DHTTYPE DHT22   // DHT 22  (AM2302)
DHT dht(DHTPIN, DHTTYPE); //// Initialize DHT sensor for normal 16mhz Arduino
SimpleTimer timer;
void setup()
{
  Serial.begin(9600);

  EspSerial.begin(ESP8266_BAUD);
 

  Blynk.begin(auth, wifi, ssid, pass);

    pinMode(7,INPUT);
    pinMode(12,OUTPUT);
    pinMode(13,OUTPUT);
  dht.begin();

}

void loop()
{
    float h = dht.readHumidity();
  float t = dht.readTemperature(); // or dht.readTemperature(true) for Fahrenheit

  if(t>=33)
  {

    digitalWrite(12,HIGH  );
  }
 
  else
  {

    digitalWrite(12,LOW);
  }
int moisture = analogRead(A3);
if(moisture>=600)
  {

    digitalWrite(13,HIGH);
  }
 
  else
  {

    digitalWrite(13,LOW);
  }

  // You can send any value at any time.
  // Please don't send more that 10 values per second.
  Blynk.virtualWrite(V4, h);
  Blynk.virtualWrite(V5, t);
  Blynk.virtualWrite(V6, moisture);
  // Setup a function to be called every second
  Blynk.run(); // Initiates Blynk
  timer.run(); // Initiates SimpleTimer
}
