The population of India has reached beyond 1.2 billion. If the population goes on increasing with the present rate then after 25-30 years there will be a serious problem of food, so in order to meet the demand of food one has to give more emphasis on the development of agriculture. Today, man has occupied all the suitable land but the land located far away from the human settlement is not developed properly and not utilized fully because it requires more manpower, time and expenditure. But now a days it is possible to pay more attention with the help of modern available controlled devices like computer, microprocessor, sensor, integrated circuits and microcontroller.
In the present work a Microcontroller based controlled remote irrigation system is developed for the agricultural plantation. The developed system is placed at the remote location and required water provides for plantation whenever the humidity of the soil goes below the set-point value. Humidity sensor provides proportional amount of output with change in humidity, which is compared, to the set-point and the data is taken through the channel. If the set-point data is high, then after motor is turned ON, which provides water to the plant till the humidity goes above set-point value. After reaching the humidity above set-point value motor is turned OFF and scans the next channel. This provides right amount of water at right time. The required software program is developed in assembly level language.

6. MICROCONTROLLER
• A microcontroller is a selfcontained system
with peripherals, memory and a processor
that can be used as an embedded system.
• Also called Embedded Controller

7. Applications of Microcontrollers
• Used in automatically controlled devices
including power tools, toys, implantable
medical devices, office machines, engine
control systems, appliances, remote controls
and other types of embedded systems.

9. Sensors and Comparators
• Sensor is a type of transducer.
• Measures a physical quantity in order to
convert it into an electronic signal
• Sensor HIH 4030 measures relative humidity
and produces linear analog.
• Comparator compares
data with a reference value.

10. Humidity Sensors
• A humidity sensor (or hygrometer) senses,
measures and reports the relative humidity in
the air. It therefore measures both moisture
and air temperature.

16. Merits
• Highly sensitive
• Works according to the humidity level
• Can handle heavy loads up to 7A.
• System can be switched into manual mode
whenever required
• It helps to increase the production from 25 to
30 %.

17. Conclusion
• The developed microcontroller based
irrigation system can work constantly for
indefinite time period, even in certain
abnormal circumstances.
• It is also possible to correct the various
parameters through the controller
programming.
