This paper developed a Soil Moisture Forecasting (SMF) model and a Constant-moisture Automatic Irrigation System (CAIS). The SMF model used the soil moisture data at different depths in an experimental plot inside a greenhouse to infer the soil moisture level after a specific interval. CAIS integrated the SMF data with dynamic watering interval adaption to maintain soil moisture at a constant level. Most intelligent irrigation products incur high installation costs that farmers cannot afford. CAIS used a low-cost component to achieve the same functionality that is found in intelligent irrigation products. Most low-cost irrigation systems water the plants from a single point that may lead to variable soil moisture if the terrain or the soil density is uneven. CAIS divided the experimental plot into multiple virtual planting areas (VPAs) and dynamically adapted the watering interval of each VPA to balance the soil moisture of the whole experimental plot. Results showed that the forecasting error of the SMF model was less than 12 moisture levels over a scale of 1024 levels. Furthermore, CAIS maintained the soil moisture of the whole experimental plot at a constant level within ±5 error points with multiple watering points.

Abstract The role of Agriculture is important to build a nation, since more than 58% of the population in our country is dependent on agriculture that means half of the population is investing in agriculture. However, many farmers are unfamiliar with intelligent irrigation systems designed to improve the water used for their crops. The proposed system is to precisely monitor the distribution of the water to crops. This IOT based system has a distributed wireless network of soil moisture sensors to monitor soil moisture. Other sensors such as temperature, humidity, rain, IR, LDR, foot. The gateway device also processes the detector’s information and transmits the data to the farmer. An algorithm was developed using threshold values for soil moisture and nutrients, and these values were programmed into a node com-based gateway to control water for irrigation. Complete sensor data is sent to the free cloud using NODEMCU and displayed on websites and apps. This proposed work presents extensive research on irrigation systems in smart agriculture.

Design Analysis

This work considers the design analysis of a low-cost microcontroller-based irrigation controller capable of managing irrigation for a small area of land based on real-time values of soil moisture and temperature. The method employed is to continuously monitor the soil moisture level to decide whether irrigation is needed, and how much water is needed in the soil. In particular, the microcontroller based circuit device performs the action of irrigation management. Specifically, it does this by continuously monitoring the moisture content of the soil, and comparing the values with two set reference values; the upper-limit, and lower-limit moisture content values, and then induces the corresponding action required. When the soil moisture content goes below the lower-limit value set by the user, the system observes this and begins irrigation action. Results obtained show that this design is cost-effective, and guarantees efficient water supply and effective labor management. Also, irrigation test results show that the duration of spray largely depends on the soil texture, grass identity and moisture content. In particular, sprinkler irrigation method in loamy soil took longer than in sandy soil, while clay soil irrigation took the longest time.

Este trabalho teve como objetivo desenvolver um sistema de irrigação inteligente para pequenas hortas. A automação foi montada e verificada no sistema de irrigação da horta didática da Universidade Federal do Ceará em um canteiro de 10 m2, onde foram cultivadas espécies olerícolas. Os dados referentes a umidade do solo foram obtidos por um Arduino através de sensores de umidade resistivos, utilizados no sistema de irrigação, cujo objetivo foi manter a umidade do canteiro. Através do monitoramento constante o sistema foi capaz de armazenar informações de umidade e acionamento da irrigação. Assim, comprovou-se a eficácia, a viabilidade e a aplicabilidade do sistema de controle, pois esse foi capaz de monitorar as variações de umidade do solo, acionando e desacionando a válvula no momento ideal além de armazenar a data, hora e umidade de quando a irrigação foi iniciada e concluída. Palavras-chave: Automação, irrigação de precisão, transferência de tecnologia.  LINO, D.

S.AUTOMATED IRRIGATION WITH ARDUINO DEVELOPMENT PLATFORM IN THE DIDACTIC HORTA OF THE FEDERAL UNIVERSITY OF CEARÁ  2 ABSTRACT The irrigation in small vegetable gardens, for a long time, was made in a simple and manual way, however, nowadays, there are ways to optimize the irrigation process in a way that reduces the water consumption, fulfill the crop needs and better use the time of the worker. This work aims at an intelligent irrigation system for small vegetable gardens. The automation was implemented and verified in the irrigation system of the didactic vegetable garden of the Federal University of Ceará, in a 10 m2 plot, where vegetable species were cultivated. The data concerning soil moisture were gathered using an Arduino platform through resistive humidity sensors, used in the irrigation system, whose objective was to maintain the garden humidity. By constantly monitoring the system was capable of storing moisture data and activating the irrigation system. Thus, the effectiveness, viability and application of the control system was confirmed, since it was able to monitor the soil moisture variations, activating and deactivating a valve when convenient, and also being capable of storing the date, time and humidity of the moment when the irrigation process was started and completed. Keywords: Automation, precision irrigation, technology transfer.

Agricultural Yields

In spite of technological advancements, the farm productivity of Indian agriculture is still on the lower side. The underlying reason for poor farm productivity in India is due to the inefficient usage of agricultural inputs, resulting in low or poor-quality agricultural yields. Water happens to be one of such imperative agricultural input that has a huge impact on agricultural productivity. Precision agriculture systems can take care of irrigation requirements by optimally and efficiently using irrigation water for producing crops having superior quality and quantity. This work proposes a smart irrigation system that can efficiently manage the water requirements of the crop for its optimal growth. The irrigation schedules are developed using a feed forward neural network model that can predict the variation in the soil moisture considering the environmental factors such as temperature, humidity, atmospheric pressure, and the rain. The results indicate the effectiveness of the developed system in predicting the soil moisture with mean square error as low as 0.13 and the R value as high as 0.98.

The proper usage of water is essential in irrigation because of the shortage of water. The shortage of water is due to lack of rain and continuous supply of water for irrigation as a result lot of water got wasted. It is very much essential to manage the use of water efficiently. The main objective in this project is to watering crops automatically by monitoring soil moisture for supply water based on the requirement and to maintain the water level in the overhead tank. This system suits for all climatic conditions. This project proposed on the usage of automatic irrigation system based on Arduino board, soil moisture sensor, float switch and solar panel. This automatic irrigation system senses the moisture content of the soil and automatically switches the solenoid valve and the overhead water level is monitor by float switch sensor and the power the required for the entire system is generated by using the solar panel. It will automatically control the water level in the tank also. The Global system for mobile communication (GSM) module sends the message, whenever the valve is turn ON and OFF. This project is fully automatic to support farmers, provides water as required, deploys renewable energy, minimize man power, less space, low cost and user friendly.
