FIELD MONOTOTING SYSTEM- TEMPERATURE AND SOIL MOISTURE

One of the important profession in India is farming so it is essential to look out for automation in field work to reduce man power. Manual watering of the plants in a garden requires more labor and time. Also, it is difficult for a man to identify when and how the soil needs water by observing with a naked eye. Throughout the earlier years many devices and technologies has been utilized to provide automation in farming and accordingly to reduce efforts of farmers.Various applications provided a solution to reduce manpower like Camera based detection of disease on plant, automatic irrigation system, smoke and fire detection, seed plantation machine.The purpose of the project is to build a multipurpose agricultural robot which can perform various operations on field. Here this project focuses on farming work features like automatic irrigation system, monitoring of the field using parameters as temperature, humidity and soil moisture these two parameters are monitored from field and transmitted through Bluetooth Connectivity. 
 As irrigation is the main part of agriculture. Labor saving and water saving technology is key issue in irrigation. Microcontroller based automatic plant irrigation system allows a simple and low cost method for irrigating the crops automatically. In the proposed system we use Bluetooth Connectivity. Here we have three sensors that are soil moisture,Humidity and temperature Sensors for irrigation purpose and also to control the agriculture Parameters. When any of these sensors generates a low signal, the controller enables the Bluetooth to send the message of the particular parameter and display the status of sensors in Android Mobile. Bluetooth is used to communicate with the user about the exact field condition. The soil moisture sensor checks the moisture content in the soil with the help of probe inserted in the soil at the plant. The value is generated by short circuiting of two probes in the soil.This system introducing automatic irrigation system by using Arduino Uno controller. For wireless communication Bluetooth is used between famer handset and robot which transmits status of sensors as well as receives commands from handset to turn on and off the motor pump. Soil moisture sensor gives information about moisture level of the soil which will then transmit to mobile unit through Bluetooth module.
