Smart Farming System

This project aims to develop a Smart Farming system which provides the means of getting live data from farm such as temperature, humidity, soil moisture etc.


Introduction

Smart technologies are the combination of hardware and software here the hardware components are like temperature & humidity sensor, PIR sensor and soil moisture sensor connected with an arduino where as arduino IDE is used as the software . Arduino receives status of different parameters from the sensors connected to it and send it over mobile phone via GSM module.

The screenshot provided above shows an example of message received by the user about the various parameters of the farm.

The system is equipped with a PIR sensor and buzzer which helps in detecting if any animal breaks into field and destroys the farm or if any theive enters the farm.


Hardware Required

 

Arduino Uno

Arduino GSM shield V2

Soil moisture sensor

Temperature & Humidity sensor

PIR sensor

Buzzer

Jumper Wires

 

Software Required

 

Arduino IDE

 

Connections

As shown in the above circuit diagram different sensors have to be connected with the arduino using jumper wires.

  Serial.print(" ");

  delay(1000);                 

  Serial.print("AT+CMGF=1 ");   

  delay(1000);

  Serial.print("AT+CMGS="+XXXXXXXXXX" "); //replace X with 10 digit mobile number   

  delay(1000);

  Serial.print((String)"update->"+(String)"Temprature="+t+(String)"Humidity="+h+(String)"Moisture="+m);

  delay(1000);

  Serial.write(0x1A);

  delay(1000);

  mySerial.println("AT+CMGF=1");//Sets the GSM Module in Text Mode

  delay(1000);

  mySerial.println("AT+CMGS="+XXXXXXXXXX" "); //replace X with 10 digit mobile number   

  delay(1000);

  mySerial.println((String)"update->"+(String)"Temprature="+t+(String)"Humidity="+h+(String)"Moisture="+m);//message format

  mySerial.println();

  delay(100);

  Serial.write(0x1A);

  delay(1000);

  c++;
