 Abstract

In India, the grading of onions is done manually or with a motorized grading equipment which prolongs the grading process and raises the labor costs. When an onion deviates from being perfect globular shape it has been discovered that grading mistake will increase therefore it is essential to the develop system for grading that is more precise and effective. The main objective of the project is to grade onions in three grades i.e., 20-40mm(small), 40-60mm(medium), >=60mm(large) accurately and to make a portable system with reduced processing time. The proposed system presents an effective method that can help the classifying, has high accuracy and fast grading time that could meet industrial needs. The conveyer belt is build using Flexible Rubber of 2m length and 20cm width, Dc motor with 300Rpm and 12v geared, Roller of 6cm inner diameter. V pulley is used to support the motor movement, flat conveyor belt is considered having plywood as the supporting bed. Onions are passed through the conveyor belt where the sensor system is attached alongside of the belt to determine the diameter of the onions. The sensor system consists of ultrasonic sensor integrated using Arduino uno as controller. The data acquired from the sensor system is been processed using serial communication for sorting mechanism, in sorting mechanism onions are been graded into small, medium and large accordingly. Flapping system made up of servo motor and linear flaps is used to divert the onions to a particular direction based on the position of baskets. Onions are collected at three separate baskets kept at the end of the conveyor belt system. This project shall have an application in both farming and the upliftment of agricultural sector and the life of farmers. The proposed Electric vehicle control system is implemented on a prototype tricycle chassis. Overall, the paper proposes a cost- effective motor drive control system for electric vehicles, with closed-loop PWM control and an electronic differential control loop. It offers efficiency, reliability, and a smooth driving experience, making it an ideal solution for sustainable transportation and a significant contribution to the field.

 Abstract

A linear actuator is a device which converts rotational motion into push or pull linear motion, which can be used for lifting, dropping, sliding, or tilting of machines or materials. Linear actuators work by moving an object or piece of equipment in a straight line, moving an object accurately and repeatably if required. The project is intended to design XY linear actuator which can carry the payload in X and Y direction. Lead screw mechanism is used to provide the linear actuator in XY direction using two stepper motors. The drive signals for the stepper motor is provided using CC3200 MCU (microcontroller unit). CC3200 is enabled with IEEE802.11 for wireless connectivity and a Graphical User Interface is provided through a web page with HTTP protocol for controlling XY linear actuator. Additionally, a webpage is developed for controlling a XY linear actuator. The experimental results shows 0.1062 mm and 0.1437 mm of error for X and Y axis respectively.

 Abstract

Rain is an essential part of the water cycle that transfers water from the atmosphere to the surface, sustaining life. For many human activities, including irrigation management, hydrological monitoring, water resource management, and flood prevention, accurate rainfall data is crucial. Traditional approaches to monitoring rainfall data, however, can be inefficient and time- consuming. A reliable system for predicting rainfall is necessary because global climate change has also altered rainfall patterns. Effective sensors for measuring rainfall are rain gauges. However, it can be difficult to accurately predict when it will rain. Unexpected or significant rainfall can harm crops and property, which has an impact on the economy. Therefore, early warning systems and reducing risks to life and property, particularly in agriculture, depend on improved forecasting models. The goal of this project is to create a system for predicting rainfall using machine learning and artificial intelligence. The system aims to make machine learning techniques easy to use for non-experts in the field and to compare them. For increased accuracy, the project makes use of a sizable dataset of historical weather information. The system can forecast rainfall amounts and provide advance warnings to lower the risk of loss. Since the people of this country are primarily dependent on agriculture, this prediction system is crucial to managing agricultural farms and utilizing water resources efficiently.

 Abstract

Agriculture is a critical sector for the Indian economy. Areca nut is one of the major commercial crops in India, and operations like spraying pesticides and fertilizers can be harmful and tedious for farmers. The scarcity of labour in agriculture has become a major concern in recent years, particularly for areca nut cultivation. Areca nut trees require frequent climbing for tasks such as preventive spraying against fungal diseases and nut harvesting. In addition to disease, farmers must also contend with the health risks associated with pesticide exposure. This paper aims to design a user-friendly agriculture robot that can assist farmers in risky tasks, such as pesticide/fertilizer spraying. The proposed system involves the automation of farm activities, which can be controlled by the farmer using a joystick. It uses MY1016ZL high torque motor and Cytron Smart Drive MDDS30 Dual 30A Motor Driver to control the motor. A FlySky FS i6 transmitter and receiver combination is employed for controlling the robot. The robot frame is equipped with a nozzle attached to a rubber pipe, which is employed to spray pesticide during operations. The proposed solution serves as a dependable means of resolving the issue of labour shortage, ultimately leading to an improved quality and yield of the produce.

 Abstract

The concept of microfinance has emerged in India as a new mechanism and has become the most promising strategic weapon for attacking poverty by way of providing development funds to the poorest of the poor target groups. The idea of micro finance is very simple. In the most simplistic way, it can be termed as 'banking for the poor'. It is defined as a provision of thrift, credit and other financial services and products of very small amount to the poor in rural, semi-urban or urban areas for enabling them to raise their income levels and improve living standard. As per the definition of international labour organization(ILO), microfinance is an economic development approach that involves providing financial services through institutions to low income clients. It is the provision of a board range of financial services such as deposits, loans, payment services, money transfers and insurance to poor and low income households and their micro finances.
