CURRENT SCENARIO

o In India, Agriculture plays contributes 14% of the countrys GDP.

o Scorching summers threatens our planet every year, our farmers are unable to cultivate

our traditional crops at their suitable seasons.

o

On other hand farmers are wasting water abundantly . This leads to the scarcity of water atthe time of requirement

o This set-up involves visual inspection of the plant growth, manual irrigation of plants,

turning ON and OFF the temperature controllers, manual controlling of waterpump.

o It is time consuming, vulnerable to human error and hence less accurate and unreliable.the present day situation motivated us to do this innovative project.

o At present farmers are doing the irrigation manually, but in our project it is designed to

irrigate automatically.

PROBLEM DEFINITION

INTRODUCTION

The system is an embedded system which will closely monitor and control the microclimaticparameters of a greenhouse on a regular basis round the clock for cultivation of crops and to

To eliminate the difficulties involved in the system by reducing human intervention to the bestpossible extent

The system comprises of sensors, Analog to Digital Converter, microcontroller. When any of the above mentioned climatic parameters cross a safety threshold which has to be

maintained to protect the crops, the sensors sense the change and the microcontroller readsthis from the data at its input ports after being converted to a digital form by the ADC. Themicrocontroller then performs the needed actions by employing relays until the strayed-outparameter has been brought back to its optimum level.

As the system also employs an LCD display for continuously alerting the user about thecondition inside the greenhouse, the entire set-up becomes user friendly.

For automatic irrigation controller, we need to measure different parameters i.e. atmospherictemperature, Humidity, Radiation, Soil moisture etc. The key objective of this project is toreport on a developed indigenous low cost irrigation scheduler which performs user definedfunctions and outputs commands

Project can be extended to open field level by making following

changes:

o LED will be replaced by Halogen

o Fan will be removed as air cannot be controlled

Fertilizer sensors can be used to monitor& control the

quantity of fertilizers

Speaking voice alarm can be used instead of SMS

Multicontroller system can be developed


11/11

1. Low cost system, providing maximum automation.

2. Closed loop design prevents any chances of disturbing the

greenhouse environment.

3. User is indicated for changes in actuator state thereby giving anoption for manual override.

4. Low maintenance and low power consumption.

5. The system is more compact compared to the existing ones,hence is easily portable.
