INTRODUCTIONINTRODUCTION In the world of advance electronics, life of

human beings should be simpler hence to make life more simpler and convenient, we have made “AUTOMATIC PLANT IRRIGATION SYSTEM”.

A model of controlling irrigation facilities to help millions of people. This model uses sensor technology with microcontroller to make a smart switching device .

The model shows the basic switching mechanism of Water motor using sensors from any part of field by sensing the moisture present in the soil.

WORKINGWORKING This project consist of three stages namely

sensor circuit, microcontroller circuit and motor driver circuit.

Sensor circuit senses the condition of soil and compares the voltage with the reference voltage i.e.,5v this is done by the IC timer 555.

If the condition of soil is less than the reference voltage i.e.,dry then the IC timer send the high signal (logic ‘1’ ) to Microcontroller PORT 39, this will turn ‘ON’ the motor driver circuit (1293d) which connected at PORT 21 and make motor to pump water to the field.

When the soil becomes wet i.e, greater than reference voltage(5v) the timer send logic ‘0’ signal to microcontroller which will turn ‘off’ the motor driver circuit and stop pumping water to the field.

The condition of motor and soil are displayed in the LCD screen.

In this way the process is repeated, whenever there is need of water to the field.

MERITSMERITSSaves water - Studies show that drip irrigation systems use 30 -

50% less water than conventional watering methods, such as sprinklers.

Improves growth - Smaller amounts of water applied over a longer amount of time provide ideal growing conditions. Drip irrigation extends watering times for plants, and prevents soil erosion and nutrient runoff. Also, because the flow is continuous, water penetrates deeply into the soil to get well down into the root zone.

Discourages weeds - Water is only delivered where it's needed.Saves time - Setting and moving sprinklers is not required. A

timer delay as per environment can be added to the system for automatic watering.

Helps control fungal diseases, which grow quickly under moist conditions. Also, wet foliage can spread disease.

Adaptable - A drip irrigation system can be modified easily to adjust to the changing needs of a garden or lawn.  

DEMERITSDEMERITS This is applicable for only large

farms. Have limited life after

installation due to the detoriation of the plastic component in a hot, arid climate when exposed to ultraviolet light.

APPLICATIONSAPPLICATIONSIrrigation In Fields.Irrigation In Gardens, Parks. Very Efficient For Paddy, Rice

Fields.

FUTURE EXTENSIONFUTURE EXTENSIONWater resources can be utilized efficiently and

effectively based on various other parameters so that agricultural sector becomes more productive. Automatic drip irrigation at different seasons is another future scope. Water is allowed to the field of crops depending upon the particular season. Some more parameters such as plant growth at different stages, whether condition are to be taken into account to determine the water requirement for the crop This will improve agriculture leading to economical development of our nation.

CONCLUSIONCONCLUSIONIn present days especially farmers are facing

major problems in watering their agriculture fields, it’s because they have no proper idea about when the power is available so that they can pump water. Even after then they need to wait until the field is properly watered, which makes them to stop doing other activities. Here is an idea which helps not only farmers even for watering the gardens also, which senses the soil moisture and switches the pump automatically when the power is ON.
