It provides food as well as large employment. So, modernization of agriculture can boost up the crop yield and also helps in making agriculture simple, automatic and effective. Indian agriculture is dependent on the monsoons which is not a reliable source of water. Therefore there is a requirement of an automatic irrigation system which can provide water to the field according to their soil types. These requirements made us to come out with this project. This project initially test the moisture content of the soil, using analog soil moisture sensor whose output will be fed as an input to the microcontroller. The Microcontroller will play a major role by turning the motor ON or OFF based on the analog soil moisture sensor’s output. When the motor is turned on by the microcontroller, it will pump the water from the ground. The pumped water is stored in the tank. The GSM module helps in sending a message to the farmer about the condition of the motor. The water when reaches the outlet of the tank, will rotate the turbine and thus the motion of turbine will help us in generating power based on the hydro electric power generation principle. Thus with the help of this project, many youngster can adopt agriculture with the latest technologies.

INTRODUCTION This project ensures that water is distributed to the field based on the moisture content of the soil. The Analog moisture sensor helps in checking the moisture content of the soil and its output will be fed as an input to the microcontroller. The PIC microcontroller will act according to the sensor’s output. If the sensor’s output match the required moisture value, then the motor will remain turned off and if the sensor’s output does not match the required moisture value, the motor will be turned on. When the motor is turned on, it will pump the water into the tank. When the water flows, it will rotate the turbine placed at the outlet of the tank. Thus the motion of turbine can be utilized for power generation from the field, based on the hydro electric power generation principle. The generated power can be stored and used for home appliances. Thus the agricultural field can be made fully automatic with the help of microcontroller. Since we are depending on machines, every stage will be reported to the farmer of the field with the help of GSM modem and additionally farmer will be given multiple choices on his mobile phone. Thus the farmer can control the field at every stage by selecting the required option. II.
