Irrigation system in India has given a high priority in economic development. Many new concepts are being developed to allow agricultural automation to flourish and deliver its full potential. To take full advantage of these technologies, we should not just consider the implication of developing a new single technology but should look at the wider issues for complete development of a system. The main aim of this project is to build a smart agriculture monitoring system using Arduino UNO and GSM. This project makes a use of Soil moisture sensor is used to measure the moisture level in soil, DHT11 sensor is used to measure the temperature and humidity at field. Here we are using A9 GSM module to send the alert message to the predefine mobile number if the system detects any abnormality like high/low level of moisture, temperature and humidity. The main controlling device of the whole system is Arduino micro controller. GSM module, Soil moisture sensors, DHT11 Temperature and Humidity sensor, LCD display and GSM are fed to the Arduino microcontroller. The Arduino controller continuously reads the data from sensors and monitors this data on LCD module. When any sensor data exceed threshold value this system send the alert SMS to the user mobile. So the user can check his field every time and keep the field safe.            

The main objectives of the project include:  

1. It overcomes the difficulty of farmers in farming their land in every season no matter what is the weather that day.
2. Automatic Soil moisture, humidity and temperature sensing system.
3. Visible alerts using LCD display.
4. SMS based alerting system.
5. To archiving this task using arduino UNO microcontroller.

           

The major building blocks of this project are:  

• Power supply.
• Arduino UNO.
• Soil moisture sensor.
• Humidity sensor.
• GSM.
• LCD display.

         

Software’s used:  

1. Arduino IDE studio compiler for Embedded C programming.
2. Express SCH for Circuit design.
