To meet this growing demand, farmers are forced to grow more crops with the help of irrigation systems. This farming system uses a pump mechanism that requires the presence of an individual to control the water level. Sometimes it is not possible for the farmer to always be present. It causes difficulties in managing all agricultural activities. On top of this, climate warming is causing lakes and rivers to dry up rapidly, while rapid urbanization and water pollution are putting enormous pressure on the quantity and quality of available water. In conventional irrigation system a lot of water is wasted which can be reduced with effective usage and proper management. Adhering to this problem we want to propose a solution in the form of a mobile application which includes features such as automation of water pump operation which helps in effective monitoring of water level, prediction of crop to be sown, marketing of harvest, make the current product rate available and ensure profitability by identifying potential buyers. The application will also provide information on the latest schemes introduced by the government. Using NodeMCU proves to be more convenient than Raspberry Pi and in turn benefits the farmer.

Get an original essay Introduction India's rapidly increasing population requires increased food production. Our Indian cultivation and marketing system is totally dependent on conventional systems and methods. While rapid urbanization and growing demand are putting enormous pressure on the quantity and quality of agricultural production, using the conventional system and methods it is very difficult for farmers to manage all agricultural activities and also get adequate returns on investments. Conventional methods mainly use irrigation for agricultural activities. Irrigation is the controlled application of water to crops at necessary intervals. It is mainly used to satisfy water needs not satisfied or partially satisfied by rainfall. Many different traditional irrigation methods are still used, such as surface water (river, streams and soil), sprinkler irrigation and drip irrigation to satisfy the plant's thirst. In India, the existence of irregular topographies causes variations in temperature, altitude and rainfall in the regions. Therefore, the methods of traditional water use and irrigation systems have evolved very differently over the years in different places. Besides irrigation, crop management is also very important in agriculture. Crop management refers to the monitoring of agricultural parameters to improve crop growth and yield of agricultural products. Growing the right crops at the right time and in the right place plays a very important role in agriculture, which is an essential part of crop management. In the current scenario, farmers have limited knowledge of the crop and soil conditions required for each type of crop. When these conditions are not met depending on the type of crop,this affects both the quality of the crop and the yield. After crop management, the next important part is marketing the crop. This involves the sale of the agricultural products obtained. Today's agricultural marketing undergoes a sequence of transfers: from farmers to intermediaries and finally to customers. Therefore, farmers do not get the right return on their investment. Literature Review Previous research papers on irrigation system automation and soil parameter monitoring were reviewed for the development of the proposed system. The following subsection provides a brief summary of the research papers. The main purpose of the irrigation system is to water the plants according to their needs. This need depends on several parameters such as soil temperature, humidity, soil pH level, etc. These values ​​play an important role in deciding when to provide water to the crop. The basic system uses a soil temperature sensor and a humidity sensor to collect all the required data. This data is collected by the microcontroller, and based on the data received, it will make decisions. This system uses a relay that will turn on the water pump. Uses the LCD display to show the current status. The main disadvantage of this system is that it is not suitable for farms distributed over a large geographical area. When the area to operate on is large, the need for a wireless sensor network arises. The system divides the vast geographical area into different zones. Each zone consists of a wireless sensor unit that uses different sensors such as temperature, soil moisture, humidity and water level. Each of these zones reports to a gateway unit, which manages all the sensor information, takes appropriate actions and transmits the data to a web application. Sensor values ​​can be monitored on the web page. To verify this data the user must have access to the web application, which is not always possible. To overcome this problem, GSM system is used. The system will use GSM messages to control system automation. This replaces the need for Internet connection. Users of this system are able to monitor the system using GSM messages and a simple Android application. It is designed to allow users to access the system at any time eliminating the need for a web application. These messages are used to control the system and monitor information using the Android application. The Android application will read the data contained in the message and display it to users. The disadvantage of this system is that it covered a low range of agricultural land and was not economically accessible to all. Proposed SystemThe objective of this project is to automate the irrigation work to some extent and help the farmer to make beneficial decisions such as crop selection and crop marketing. Modules A smart irrigation system with crop management and marketing is available to users in the form of a mobile application that can be installed on mobile phones and some field hardware. The modules involved in the system are as follows: Automatic Watering Module This module automates the irrigation system by automatically turning water on and off as per the soil requirements based on soil temperature and humidity. Crop Management Module The Crop Management Module will improve the decisions making of the farmer in selecting the suitable crop to grow in the farm for the highest yield and yield. This module will monitor various aspects of the soil and suggest to farmers the most suitable crop for the soil. Marketing module.
