The aim of this project is to develop techniques in agriculture automation to flourish and deliver its full potential. This system designed by using arduino microcontroller to overcome limitations of agriculture farming and Urban gardening about supplying of water to plants by drip system with the available water tables. In our system we use Arduino microcontroller, motor pump, soil moisture sensor. The motor pump works according to the soil condition that is soil wet or dry; if soil is wet motor stops otherwise motor run to give water to plants. The status of motor is displayed on LCD. Different sensors are connected to the controller to verify the temperature. SMS will be sent to the owner in case of any critical situation. It is connected with cloud services and via cloud users can check the status of siol using Apps which uses gis to present the moil moisture and related data based on loacation. Keywords: Arduino, soilmoisture, temperature, Cosensors, GSM, motor pump.
Introduction
Irrigation is the main problem in agriculture and urban gardening in the countries which are in developing stage. The main cause is low rainfall and also lack of care due to this more land is not irrigated. Another very important reason is unplanned usage of water resources by this way more water gets wasted. By the drip system, water is supplied to the plant zone only thus saving a large amount of water. Automatic irrigation system can supply water to plants whenever they are in need of water at regular power supply intervals. Here no need of turning ON/OFF of valves. By this automatic irrigation system, watering plants at exact time based on soil condition which will improve crop growth by taking water and minerals from soil when needed. The aim of the project is to create a sensor network based on low cost soil moisture, temperature monitoring system which helps to track the moisture of the soil and temperature in real time and allow water to the plants based on the detecting values and the type of crop.
Working
The soil moisture sensor senses the moisture content of the soil and as soon as the necessity of planting water it sends the notification to the user. It has two conductors which are separated by small distance commonly called as electrodes. It has Vcc,ground and signal pins along with the digital pins which provides the output as high or low. The signal pin gives the analog value which is proportional to the amount of moisture in the soil. The two electrodes are inserted into the soil to get the moisture level of the soil. There will be high resistance when the flow of electricity is high and the resistance will be low when the flow of electricity is low. When the resistance is high the moisture content wil be high and the moisture content will be low when the resistance is low.
Working Procedure
Many advanced techniques has been introduced in agriculture automation to flourish and produce its full potential. This system designed by using Arduino microcontroller to overcome limitations of agriculture farming and gardening system about supplying of water to plants by drip system with the available water tables. In our system we use Arduino microcontroller, motor pump, soil moisture sensor, LDR. The dielectric permittivity of the surrounding medium is measured using the capacitance of the soil moisture sensor. The dielectric permittivity is the purpose of the water content in the soil. It is proportional to the voltage created by the sensor and also to the water content of the soil.The sensor averages the water content. The Soil Moisture detector is employed to live the loss of moisture over time because of evaporation and plant uptake, observe optimal amount of soil moisture contents for various species of plants, examine soil moisture content to limit irrigation in this experiment.
