Abstract Agriculture is one of the major sources of economy in the country. Precision Agriculture is already in implementation in other countries but there is a need to implement, improve and evolve IoT(Internet of Things) and cloud computing technologies for better production of the crop. There is a steady increase in demand with population growth. Modernization in agriculture reduces dependency on individual human labor and land. The technology allows operational devising and accelerates verdict making on Farms. IoT allows us to accumulate surrounding data, stock it, concoct it and disseminate the information. The adoption of cloud computing has undergone a huge rise in need and would continue to grow in the coming future with improved cloud hosting and processing dexterities. AI(Artificial Intelligence) and IoT is a great lead as a solution to increased productivity. The data through IoT devices is made available publically for research purposes as data sets and is processed and examined for further prediction related to the crop being produced. The Traditional Technique of farming does not involve any process such as seed selection, soil analysis, weather analysis, vegetation analysis, Nutrient analysis if all these factors are taken in care, this all would bring a drastic change in the society. The System also has a block-chain based shipping system to ensure proper distribution without any wastage. Though the pen-paper tradition is hard to be replaced but minimizes a lot of work, moreover the analysis of manual work required can also be analyzed. A more intricate approach to IoT products in agriculture can be represented by the so-called farm productivity management systems. They usually include several agriculture IoT devices and sensors, installed on the premises as well as a powerful dashboard with analytical capabilities and in- built accounting/reporting features. In addition to the listed IoT agriculture use cases, some prominent opportunities include vehicle tracking (or even automation), storage management, logistics, etc.

1. INTRODUCTION

   With the population boom, there is a rapid increase in the demand for food and agricultural stocks and cultivation process to improve yield, cost-effectiveness, and quality of crops/agricultural products being produced with new technology such as the Internet of Things(IoT) and Artificial Intelligence. There is a need to increase yield, effectiveness and enhanced production of land per unit area taken under deliberation. It is necessary to embrace new technologies to overcome these problems. There are various benefits associated with the enactment of new technologies which include: increased productivity, proper crop distribution, Crop pattern suggestion, proper utilization of resources such as

   Fertilizers and manures using the technique of Automation and AI model.

2. OBJECTIVE

   The Motive of paper is to detect and determine the nature and quality of soil based in a particular area, considering the toxicity level at present instance of time and predict its future value using AI model. The Main objectives of the paper are:-

   1. We have a limited amount of resources and their proper utilization is a subject of great concern, whether its the utilization of water or utilization of minerals from ores all this indirectly affects our lives.

   2. Moreover, there is a lack of research data in this field, this would produce a huge collection of data for the farmers.Data, tons of data, collected by smart agriculture sensors, e.g. weather conditions, soil quality, crops growth progress or cattles health. This data can be used to track the state of your business in general as well as staff performance, equipment efficiency, etc.

   provides the users with an LXDE desktop background. The Pi ingests not have a great deal of processor speed or memory, but it

   does have sufficient support to run LXDE and some of the applications like the simplistic Epiphany web browser and several more further.

   Arduino Software – The Arduino Integrated Development Environment (IDE) is a cross-platform application (for Windows, macOS, Linux) that is written in functions from C and C++. Arduino is an open-source electronics platform based on easy-to-use hardware and software. It is used to write and upload programs to Arduino

   compatible boards, but also, with the help of 3rd party centers, other vendor development boards. The Arduino IDE supports the languages C and C++ using special rules of

   code structuring. The Arduino IDE employs the program avrdude to convert the executable code into a text file in the hexadecimal encoding that is loaded into the Arduino board by a loader program in the board's firmware. By getting inputs from sensors, Arduino senses the environment and affects or influences its surroundings with different actions and actuators. Arduino is obliged to compile and upload the necessary codes to run the UO.

   Apache Web Server – Apache web server is a free and open-source cross-platform web server software developed and maintained by Apache Software Foundation. It powers around 40% of websites around the world. It is quick, stable, and safe. It can be profoundly customized to satisfy the

   demands of many different environments by using branches and modules. In this project, this server is needed to monitor the received data and perform the

   necessary assignments after the data representation and processing. The server is what is responsible for monitoring the health of the crops and also to take control of the automated water sprinkling system. In this project, the server is hosted on the Raspberry Pi.

The offered practice is implementing the notion of IoT in the farming field by using smart sensors to make agriculture field a smarter one. The primary purpose of the project is to accumulate data of multiple nodes and to process this information. The producers will be capable to regulate the actions remotely through a mobile application as well as access the accounts through a cloud. The design of the scheme is to generate centralize monitoring and control for the agricultural land. This can be maintained and operated from any place wirelessly using a mobile device. The application user can control fundamental services of accumulation of environmental, soil, fertilization, and irrigation data; automatically associate such data and filter – out illogical data from the prospect of appraising crop performance; and figure crop forecasts and personalized product suggestions for any selective farm using the application. The system can integrate virtually any IoT device, including commercially accessible sensors, cameras, weather stations, etc. and can form a bunch of these materials which would execute it adaptable for a single user to cover a large region and reserve their data in the cloud for

performance interpretation and suggestions. End-user can get all these aspects of the field on Smartphone by an administration Smart Agro Services and can guide the operations. The sensor network is devised to acquire information concerning the climatic requirements of the farm such as Soil Moisture, Temperature, Light, and Humidity. With the help of this, the scheme will determine the operations on the field. A single farm can have various crops divided into fields. So a particular crop will have several parameters to be constrained. This, we need to have a batch that will collect data separately. These nodes are installed on various parts on the field depending upon the parameters. Each The node comprises of a microprocessor Raspberry Pi and a sensor connected to it. Sensors may be temperature and humidity sensor or soil moisture sensors. The soil moisture sensor being an analog sensor requires an ADC (Analog to Digital Converter). The data from the sensor is in the analog form and needs to be converted to digital form. Hence the raw data is supplied to ADC which in turn to digital. The digital data is in the form of voltage value and depending on voltage value the percentage of moisture in the soil is taken. The sensors are connected to Raspberry Pi. Raspberry Pi collects the data from the sensors of that node. There are multiple nodes that are placed around the field. Using the clustering technology the farmer can make accurate decisions like in which part of the field soil moisture has reduced and where to divert the irrigation system.As well as when to switch on and off the motor pumps and other devices for the parameters to be maintained. Data from all these nodes are collected and transferred to a cloud. Here, we are using the cloud service as a storage database. The Data sent to the cloud is stored in the cloud database. Farmers can log in to their respective accounts to view their history and the current data of each node. The data from the cloud is given to the mobile application. With the help of the mobile application, the farmers get ease to control various devices and record the readings from the sensors.

SMART MOBILE APPLICATION:

The planters are the end-users of this application. This application will provide full radio connectivity to the farmers for their farm. The concocted data from the cloud will be obtained by the farmers using the mobile application. The farmers will get a graphical illustration of data as well for more suitable comprehension of the parameters. With the help of this data summary, the farmers will be aware of the climatic circumstances of the farm and consequently will constrain the accessories such as light and motor pumps. Each farmer will have its own account by which he can log in utilizing an

individual username and password. New users can record using their email ID and create a new account. The farmers will get the direct readings from the sensors for the node they have selected. Based on this they will also get an alert for which device should be switched on or off. The operators can thus check for the readings and wirelessly regulate the devices for the field. Apart from this the application also provides other beneficial services for the farmers as follows:

CONCLUSION

This Paper proposed an IoT and AI-based scheme for the Agricultural Sector consisting of an assemblage of Micro- controllers, sensors, and a Consolidated Water Quality System. In this method, the data consolidated from Sensors will be transferred to Cloud for processing and Data set organization through the Internet. The real-time data will be fed into an ML algorithm after a certain fixed interval of time, based on which it would predict the soil condition of the system. For predicting the variable parameter of Soil, the Regression method would be used but checking the Toxicity of Water Anomaly detection method is most suitable.

This system will be aid provided to the farmers for digitalizing agriculture. Approximating possible work on this system may entail accumulating the data and rendering services for each crop exclusively.
