1.ABSTRACT: Effective management of water resources is of key concern in cropping systems in semiarid and arid areas. Distributed sensor-based irrigation systems provide an efficient solution to support site-specific irrigation that allows farmers to maximize their crop growth along with saving water.

2.OBJECTIVE: In the field of agriculture, use of proper method of irrigation is very important from yield point of view and scarcity of water. IRRIGATION is the most essential practice in agricultural cropping systems in semiarid and arid areas. The major concern with irrigation activities in arid and semi arid areas is the efficient water use applications and management

3.BLOCK DIAGRAM: TRANSMITTER

RECEIVER

4.METHODOLOGY: This project is developed to reduce the work load of a Former and to sense the parameters like Humidity and Moisture. After sensing those parameter depending on the scenario the ARM controller will take appropriate action and the same information will be transmitted to the receiver via XBee which is there at the transmitter. The main modules in this project are Sensors (Humidity Sensor and Moisture Sensor), ARM controller unit with LCD display and output device.

This whole model can be placed in the field for irrigation purpose. This model has two Sensors as an input device to sense the field condition with respect to moisture and humidity and depending on the parameter measured the controller will take appropriate action. And the same information will be transmitted via XBee to the receiver which is placed at the former and there also the controller activates output to indicate action which is happen in the field. This module continuously monitors the field of the place where it is placed. If the Moisture or Humidity of the field varies, then the ARM controller will activates the buzzer to convey the information.

5.ADVANTAGES AND DISADVANTAGES: ADVANTAGES: 1.All the components required are easily available. 2.It is accurate [Errors are nullified] & precise as it is Digital. 3.Low power consumption. 4.Less hardware involved and Cost Efficient. 5.Automatically controlled & Easy to use. 6. Unnecessary wastage of electricity can be controlled to a greater extend. 7.Eliminate or at least minimize runoff 8. Raise healthy plants 9.Avoid soil erosion or land movement caused from excessive irrigation

DISADVANTAGES:  In this project usage of relays leads to consume more power.  One time investment.

6.APPLICATIONS:  This project can be implemented in Home, School, Colleges, and Companies etc…  Where we have to reduce the work load of human, former and to sense the parameters like Humidity and Moisture there we can implement this project.

7.CONCLUSION: The system provides with several benefits and can operate with less manpower. The system supplies water only when the humidity in the soil goes below the reference. Due to the direct transfer of water to the roots water conservation takes place and also helps to maintain the moisture to soil ratio at the root zone constant to some extend. Thus the system is efficient and compatible to the changing environment. Also the system saves the water and improves the growth of plants.
