Managing and Planning Water Resources for Irrigation: Smart-Irrigation Systems for Providing Sustainable Agriculture and Maintaining Ecosystem Services

Smart-irrigation systems are a hot topic in irrigation management. Satellite imaging, sensors and controls, communication technologies and irrigation decision models are readily available. The price of the required technology is being reduced year after year, and its implementation in agriculture gives real-time information that allows for more accurate management of water resources. Even so, the adaptation of existing technologies to particular situations that the irrigation management is facing in different agro-environmental contexts is needed. This Special Issue addresses the application of different smart-irrigation technologies in four different research areas: (1) remote sensing-based estimates of crop evapotranspiration, (2) Information and Communication Technologies (ICTs) for smart-irrigation, (3) precision irrigation models and controls, and (4) the price of natural resources. The nine papers presented in this special issue cover a wide range of practical applications, and this editorial summarizes each of them

Development of IoT Based Smart Irrigation System with Programmable Logic Controller

Smart irrigation system is an automatic irrigation and monitoring system on agricultural land with a sensor, automation, and control technology based on the Internet of Things (IoT). This system can reduce the agricultural activities that were previously performed manually into an automatic system with a reduced human supervision. Smart Irrigation systems that are widely developed used Arduino as the controller. Arduino still lacks in response, low durability, and sensitivity to temperature change, hence requiring frequent maintenance to avoid weather disturbances, insects, and others. This paper presents a development of a smart irrigation system using a Programmable Logic Controller (PLC) as the controller and a soil moisture sensor as a humidity condition measurement tool. The advantage of using PLC as a controller is more stable and has sensor compatibility with higher accuracy. Hence the results are more consistent and accurate. The PLC system is expandable, allowing for the inclusion of more channels for sensors and other measurement instruments. The developed system can collect data on soil moisture conditions, trigger valves, and perform auto irrigation using sprinklers, reducing or even eliminating the need for human intervention. The IoT collects data from sensors and updates the data into a database system, allowing users to monitor the land conditions in real-time. The developed system was predicted to save manpower (20%) and water usage (42.47%) compared to the conventional method. Keywords: Smart Irrigation; IoT; PLC; Moisture Sensor; Sprinkle

SMART IRRIGATION SYSTEM BERBASIS ARDUINO

Based on the Batam City government program to increase the food security of Batam City so as not to depend on other regions where Batam City has been fulfilling its basic needs such as rice, fruit and vegetables, import  from West Sumatra and North Sumatra, the success of its food security program will specifically choose an island to develop agriculture because each island in the Batam Islands is not suitable to be designed as an industrial area so that the specificity of an island developed for agriculture is needed. To participate in supporting the Batam City government program in developing food security in agriculture, a good irrigation or irrigation system is needed. The problem of irrigation water distribution occurs when the amount of water available is smaller than the needs of irrigation water, especially during the dry season. So that efficient use of irrigation water is needed. The uneven distribution of water due to poor management of irrigation water sources will greatly affect the success of the production of an agricultural product. to build a smart irrigation system using soil moiture sensors and Arudino-based water level sensors, it can be seen that the prototype system can function because the components used work in the order, and the results are obtained when the sensor water level is greater than 600 then the LED lights live red and buzzer will sound loudly indicating water tank below the level, when the value of soil moisture sensor is greater or equal to 700 then the red LED light is on and the buzzer sounds low indicating dray soil conditions and the water pump / selenoid valve will be on and green LED lights will live, when the value of soil moisture sensor is smaller 700 then the live yellow LED lights show moist soil and water pump / selenoid valve conditions, and when the value of soil moisture sensor is smaller than 300 then the blue LED light will live shows Soggy soil and water pump / selenoid valve off, the prototype of the smart irrigation system has the same design as it has been made

SOLAR POWERED SMART IRRIGATION SYSTEM

Sun energy is used in solar irrigation system to operate the pump which supplies water to crops to assist growth. Cost effective solar power can be answer for all our energy needs. The solar charge controller is used to store DC power of solar panels in batteries. This battery is used for water pump automatically. It works on sunlight. It gives solution for Indian farmers due to energy catastrophe. Sun energy is used in solar irrigation system to operate the pump which supplies water to crops to assist growth.

A Variable Speed Synchronous Motor Approach for Smart Irrigation using Doubly Fed Induction Motor

Department of Electrical Engineering, College of Engineering, Jazan University, Jizan 45142, Saudi Arabia.Doubly Fed Induction Motor (DFIM) is a popular machine used in variable speed drives, and its ruggedness, reliability and simplicity of speed control make it a suitable candidate for use in smart irrigation systems. This paper studies and evaluates the performance of DFIM at different operating conditions and shows that it can be viewed as a variable speed synchronous motor. The research results reveal that DFIM can be used to control the flow rate of water in irrigation systems, by adjusting the speed of the motor to match the desired flow rate. A mathematical model has been developed to optimize the performance of the DFIM in smart irrigation systems, taking into account the specific conditions of the application. In addition, an experimental setup was built and tested to enhance the theoretical results, which showed good correlation between the theoretical and experimental results. The results of this research demonstrate the potential of using the DFIM in smart irrigation systems to improve the performance and efficiency of irrigation and to provide better control and lower costs
