admin — Thu, 11 May 2023 06:59:41 +0000

Abstract: How to irrigate agricultural systems using solar electricity is the subject of this essay. The moisture content of the soil is measured by moisture sensors in this system, and a controller employs solenoid valves to control the ON/OFF status of the water pump in line with that information. Instead of using non-renewable resources, this project makes use of solar energy. An irrigation system built on Arduino checks the condition of the field using a smartphone. Arduino receives information from moisture sensors about the moisture level of the soil. This input value will be compared to a threshold value by the Arduino in order to turn on the water pump. the user uses the GSM module to get information from the motor. The solenoid valve is used to provide the field with water in accordance with

Design and Simulation of Capacitive pressure Sensor using Intellisuite

admin — Thu, 11 May 2023 07:10:43 +0000

Abstract: The design and modelling of a capacitive pressure sensor are presented in this work. High sensor sensitivities and resolutions have been accomplished using Micro Electro Mechanical Systems (MEMS) technology. Initial information on the simulation and design of such a sensor is provided in this report. The diaphragm deformation-induced capacitance change is used in capacitive sensing. A polycrystalline diaphragm that makes up the sensor deflects when pressure is applied to it. When pressure is applied, the 211m diaphragm deflects, altering the capacitance between the polysilicon diaphragm and silicon substrate. A high working pressure range and good linearity are achieved in the simulation of the MEMS capacitive pressure sensor in touch mode. To optimise the design, enhance the performance, and shorten the manufacturing process, Intellisuite software is used to model and simulate MEMS capacitive pressure sensors.

IMPLEMENTATION OF TWO STAGE CONVERTER FOR ISOLATED PV SYSTEM

admin — Thu, 11 May 2023 18:13:54 +0000

Abstract: In places without a grid, standalone solar PV systems have come to be seen as viable solutions to electrical issues. When creating these devices, it is quite challenging to get a photoelectric system, DC-DC inverter, DC-AC converter, and control system to operate at maximum capacity. In this study, a boost converter, an inverter, and batteries with a bidirectional converter are introduced as a freestanding two stage method. In order to modify the inverter output, a unique virtual synchronous generator (VSG) controller is created and put into practise in this study. To regulate the inverter output and realise the maximum power of the PV system, the VSG element and the maximum power point tracking (MPPT) are utilised in this study. Extensive MATLAB simulations were implemented to verify and evaluate the new control strategy design in a variety of scenarios, including load fluctuations. With the help of several MATLAB simulations, the system output was assessed. Console testing was used in a hands-on experiment for the VSG. We were unable to test the full system since the laboratory lacked the necessary tools.

DEVELOPMENT OF ELECTRICALLY OPERATED TILLER MACHINE FOR CULTIVATION

admin — Sat, 13 May 2023 03:58:24 +0000

Abstract: Earlier Farmers were using Traditional farming methods which is time consuming and hardworking hence we introduce new technology called tractors which can be used as cultivator to plow/cultivate land. Generally, these machines are costlier, polluting our environment and not affordable to our Indian farmers, hence we decided to make compact portable electrically operated cultivator (Tiller) machine at affordable rate. Working of this machine is based on battery and motor mechanism which can be capable to move cutter or tiller. Rather than developing IC engine-based mechanism we prefer to work on electrically operated mechanism as it is clean source of energy and don’t pollute environment as well. Majority of our Indian farmers adopt subsistence farming in which they follow traditional farming methods. Such farming is very hardworking and not more efficient so our basic aim of this project is to developed small portable cultivator machine which turn towards modern farming methods. This report describes design, manufacturing, fabrication analysis of proposed model. Our project aims to achieve high safety, reduces human effort, increases the efficiency of the soil tiller, reduces the work load, reduces the fatigue of workers and reduces maintenance cost.

FIRE FIGHTING ROBOTIC VEHICLE USING ARDUINO

admin — Sat, 13 May 2023 16:35:51 +0000

Abstract: The goal of this thesis is to create an unmanned fire extinguisher robot and an automated system. These days, fire mishaps happen often, whether or not humans are involved. A fire incident is a catastrophe that may result in victim fatalities, property loss, and long-term disabilities. Firefighters are generally responsible for responding to fire emergencies, but they frequently face greater risks when putting out a fire, particularly in dangerous locations like nuclear power plants, oil refineries, petrol tanks, etc. They encounter additional challenges when a fire breaks out in a small, congested area because they must navigate between building remnants and other obstructions in order to put out the fire and save lives.

Plant Disease Identification and Crop Recommendation Using Machine Learning And Deep Learning

admin — Sun, 14 May 2023 15:51:11 +0000

Abstract: — Identification of plant diseases and advice on crops are essential duties for agricultural businesses. The use of algorithms based on deep learning and machine learning has become crucial due to the rising demand for food supply and the need to maximize agricultural yields. In this article, we suggest a paradigm for the use of the machine and deep learning methods to identify plant illnesses and to prescribe crops and fertilizers. The framework consists of three main components: plant disease identification, crop recommendation, and fertilizer recommendation. In the plant disease identification component, we use the image classification technique to identify the type of disease affecting the plant based on its symptoms. We then use deep learning algorithms such as convolutional neural networks (CNNs) to classify the disease accurately. In the crop recommendation and fertilizer recommendation components, we use regression algorithms to predict the yield of crops based on various factors such as soil type, climate, and the presence of plant diseases. The results of our experiments demonstrate the efficiency of our framework in accurately identifying plant diseases and recommending crops with high yields. Our approach can help farmers make informed decisions about the crops they should grow, and the diseases they should be aware of, leading to better crop yields and reduced crop losses

Abstract: The term “Smokeless Tobacco” refers to the consumption of unburned tobacco, in the form of chewing, spitting, dipping, and snuff. Consumers chew the tobaccoin the mouth and spit out the juice that builds up. Nicotine and other constituentsare absorbed in the lining of oral cavity. People of many regions, including India,Pakistan, other Asian countries, and North America, have a long history of smokeless tobacco use. Approximately 28 chemical constituents present in smokeless tobacco are carcinogenic in nature, among which nitrosamine is the most prominent. According to the National Report of Global Adult Tobacco Survey conducted in India and Bangladesh, the current prevalence of smokeless tobacco use is 25.9 and 27.2%, respectively. There are 30 different types of smokeless products available in these countries, including zarda, which contains dried and boiled tobacco leaves, limes, areca nut, additives, spices, and tannins. Oral cancer accounts for 30 to 40% of cancer cases reported in India, and the most obvious cause is the extensive use of tobacco products, consumed via smoking and/or smokeless chewing products

Abstract: The major problems that follow arise when mining cryptocurrency on standard PCs: 1. System health issues, such as system overheating 2. System availability free timing algorithm for mining 3. The ratio of electricity use to cryptocurrency coin. Although it was initially impossible to mine Bitcoin using laptops and desktops, the rising mining difficulty and the introduction of hardware called Application Specific Integrated Circuits (ASICs) designed specifically for Bitcoin mining have all but eliminated the possibility of doing so. To the best of our knowledge, there is currently no academic literature on the dynamic opcode analysis of crypto mining, hence we provide the first such practical investigation. In fact, this is the first effort of its kind to present opcode analysis on files that cannot be executed. Our findings demonstrate that dynamic opcode analysis may identify browser-based crypto mining inside our dataset with up to 100% accuracy. Additionally, our algorithm can discriminate between crypto mining sites, benign sites that have been weaponized, benign sites that have been de-weaponized, and benign sites in the real world.

Abstract: Due to scarcity of fossil fuel in future and its detrimental effect on the environment, an alternative energy has to be discovered. Wind power is clean and sustainable natural resources that has yet to be fully utilized in the automotive industry. Also, the sun is probably the most important source of renewable energy available today. The hybrid system has been designed and installed to generate power which combines wind turbine and solar panel. The hybrid model system is renewable energy system, which helps conserve energy by reducing the use of fuel in vehicle. Hence developing a new method for the economical evaluation of Hybrid Systems for electricity production. This project proposes a hybrid electric vehicle (HEV) system which can resolve the major troubles of pollution. Wind and solar are the commonly used renewable energy resources. Nowadays hybrid electric vehicles (HEVS) are energized by an internal combustion engine with the combination of one or more electric motors which use energy stored in batteries. To charge the battery, a HEV cannot plug in to off board sources of electricity. As an alternative, regenerative braking and the internal combustion engine are used by the vehicle to charge. Hence the proposed system can reduce fossil fuel use, decrease pollution, and allow renewable energy sources for transportation.
