HatwarPRIYADARSHINI COLLEGE OF ENGINEERINGINFORMTION TECHNOLOGY DEPARTMENTAbstract: – In India, Agriculture plays an essential role in developing the country. With upgradation in technology we establish a system that automate the process of irrigation such that there is systematic usage of water and create an ease of work load for the farmers Traditional methods that are used by farmers for irrigation, such as sprinkler and flood type, is not that much efficient. They results in a lot of wastage of water and electricity. Also create the problem like fungus formation due to more amount of moisture in the soil. Smart irrigation system is essential for conservation of the water and indirectly viability of the farm since it is an important commodity. About 85% of total available water resources across the world are used for the irrigation purpose. In forthcoming years this demand is likely to increase because of increasing population. To achieve this demand we must adopt new techniques which will conserve need of water for irrigation process. The idea is to focus on parameters such as temperature and soil moisture, weather. This is a smart irrigation system using IOT based on application controlled monitoring system. The main objective of this project is to control the water supply and monitor through a Smartphone.Keywords: – Smart irrigation system, IOT, water irrigation, soil moisture, weather, technology.1.IntroductionAutomation is the technology in which no human interference is required. The main objective of this project is to determine how a person can use smart irrigation system of his own budgetable facility in a less time to connect the electronic components. The smart irrigation system which is based on iot. This system will help people in their day to day activities, thus saving time and hard work this system uses sensor technology with the ARDUINO, relay DC motor and battery. It behaves as an intelligent switching system that identify the soil moisture level and irrigates the plant if necessary. The ON/OFF motor will automatically based on the moisture level of the soil. These type of smart irrigation system is easily controlled using a mobile phone. The system applicable for the small and large gardens, farms, nurseries, green houses and green roofs. This will also save time and energy, electicity as well as minimize the water loss.2.Literature reviewThere have been a lot of researches going on in the area of smart irrigation system to provide a simple and effective method of irrigation. The different kind of work done aims to the irrigation its incapable water usage missing of non – apparent field invigilate, shortage of conclusion.Monika M, B.Yeshika provides an effective method to intact sensors with Arduino and sum up with smart irrigation system. In this system the data is transferred through wifi module ESP8266 and then uploaded to cloud.[2]Azmi alzzam, Ban Alomar Proposed a system for smart irrigation system that implicate two levels of judge and make decision to turn the motor switch ON/OFF.[3]Hamza Benyezza, Mounir Proposed the system in this paper which is based on microcontroller that result in low power consumption. It is based on amount of the moisture content in the soil and then making the decision embedded in the program as implemented in the system.[4]Vaishali S, Suraj S Published the paper based on the system with smart irrigation techniques using internet of things (IOT). Here in this type of system sensors are placed in the field of agriculture then it measures the soil moisture and will be displayed on the application screen.[1]Dweepayan Mishra, Arzeena Khan Put forth about the schemes for the farmers beneficial for them. The weather forecast is displayed, so as to assure whether to start or operate the motor or not.[5]3.Proposed systemThis prototype designed for continuously monitoring the weather conditions, water level, and soil moisture and then supplying water depends on the requirement. So overall system act as a feedback system by taking input from the Soil moisture sensor and maintain the water pump. In this system we can predefine the range of values for soil moisture and for water level. The humidity and temperature sensor measures the amount of water in the soil. The soil moisture Sensor placed in the soil, it tracks soil continuously and the moment when it found insufficient water in soil with respect to a predefined value, water motor will ON to pump.4.RequirementsSoil moisture sensor: A soil moisture sensor evaluate the amount of moisture present in the soil, this is of great importance for the irrigation system. A general soil moisture sensor operating at 3.3v-5v. The volumetric content of the soil is represented in percentages which we have then converted to four levels L0-L3 where zero being driest and three being flooded. When the soil moisture happens to be L0, the motor turns on and water is pumped to the plant. Arduino: It has 14 digital I/O pins, 6 analog pins, a power jack, USB connection, reset button, and an ICSP header. The main purpose of the usage of Arduino here is to interface all the sensors and actuators conveniently. The Arduino is that where all the code is dumped. The Arduino is interfaced with the Wifi module or Bluetooth Module. Relay and pump: The relay is used to turn on and off the pump according to the water level of the soil. It is controlled by interfacing it to a microcontroller, in this case the Arduino. The pump is triggered on and off by using the relay. Wi-Fi Module: The ESP8266 is a Wi-Fi module which has functionality to the existing Arduino via the UART serial connection. This module is reprogrammed in such a way that the data from the sensors are transmitted to the cloud storage provide every45seconds. Arduino IDE: The Arduino Software is an open source that can be downloaded from the website, this is used to write codes and upload it. The Arduino software supports Windows, Linux, and Mac and is written in Java. Internet of Things: Internet of things is the internetworking of physical devices interacting with each other to collect, control and exchange information. This system is in accordance with collecting real time data values from the sensors with the objective of automating irrigation on comparison with the threshold values. The data collected can be stored on a free web services. Power supply: The power supply circuit is use to provide electric current, Which is used to convert the current coming from source to the accurate voltage, frequency, current to capacity the load.Wi-Fi Technology: Wi-Fi technology is used to update our soil parameters to the cloud to keep track of the farm status using sensors. 5.ImplementationThe soil moisture sensor is used in the system. Soil moisture sensor used to measure the moisture level of the soil. The electrode check the value of the sensor and read the temperature value sensor. The soil moisture electrode is placed in soil. If the soil moisture value is less than the alert message will be send “MOTOR ON” to the app then water will be supplied to the soil to reach the moisture level. If the soil moisture value is more than alert message will be send “MOTOR OFF” to the app then water supply to the soil will be stopped. We are using an Android app called “smart irrigation system” in which we are using “ARDUINO”. Soil moisture sensor are connected with an arduino kit to get readings of moisture of soil of farm. Then these gathered values are compared with a threshold value of moisture level and accordingly pump is being operated switch on and off. Here we are also using ESP8266 which is a WiFi module that work with a UART serial communication pin, through this commands are sent to the WiFi module, first commands are connected to the WiFi spot and later send the data to Internet. 6.ResultThrough this project we control the motor according to the soil moisture level and control the amount of water being pumped according to the soil moisture. We have made it such that the pump is turned on whenever the moisture level goes low the threshold value. In case of any error, the motor pump can be manually controlled through the app. All sensor values are uploaded on a real time basis on the cloud and can be accessed anytime.7.ConclusionThis project has designed a smart irrigation system based on IOT with sensor. It may check the moisture content levels of soil and generate moisture level data through sensors. Accordingly irrigation based decisions are taken by system automatically to start water pump for irrigation. Crop can be maintained with its suitable threshold moisture levels for better yields.8.References1.vaishali s , udhayakumar and dhivya s “monitoring system using iot” april 20172.sankar dasiga, sanjay h.a, monica m “iot smart irrigation system” October 20173.amina saidi, Hamza , mounir “smart irrigation system based arduino” November 20184.arzeena khan, rajiv Tiwari ,suchi upadhaya “automated irrigation system” February 2018
