It uses a YF-S401 water flow sensor, a 555 Timer IC, a 4026 IC, and a 7-segment display to provide accurate readings of water consumption for various sectors such as industrial, agricultural, and domestic use. The YF-S401 sensor generates pulses proportional to the water flow rate, which are processed by the 555 Timer IC in monostable mode for clean signal output. The 4026 IC counts these pulses and directly drives the 7-segment display, showing the flow rate in an easy-to-read numeric format. Additional features, such as LEDs or relays, can be integrated to alert users of abnormal flow conditions. Its simplicity, scalability, and microprocessor-free design make it versatile for critical water flow monitoring applications.

Due to this overall system efficiency reduces because of additional transformer losses. Removing this transformer lowers the system's size, cost, and increase in efficiency. This result to flow of the CMGL current i.e. common mode leakage current through parasitic capacitor formed among negative of grid & PV panels. To overcome this problem, the different inverter topology like H5 and H6 are presented in this paper. This system, modulated with unipolar SPWM reduces ripples in output-load current. A comparative study of THD contents in the H5 and H6 inverter output voltage without filter and with L, L-C, and L-C-L filter is also presented in this paper.

A multilevel inverter is frequently employed as the connection point between a renewable energy source and the electrical grid. Due to its capacity to operate at high voltage, little switching losses, low dv/dt stress, which results in low presence of electromagnetic interference (EMI) in output, improved performance, and obtained good power quality, multilevel inverters have drawn more attention from researchers. In the design of multilevel inverters today, power electronics devices are increasingly used. However, the multilevel inverter's power electronics interface leads to harmonic distortion and poor power quality. Over the past 20 years, various multilayer inverter designs have been put out in an effort to reduce these harmonic distortions. A single-phase solar-integrated 25-level H-bridge multilevel inverter is suggested in this paper. To meet load demand, it is based on twelve independent solar PV arrays. It is recommended to use a hybrid topology to reduce the number of components and harmonics (like clamping diodes, DC Bus capacitor). The proposed model has been put into practice using MATLAB/Simulink.

The technological progressions in the present world has affected most of the processes of efficient and communal infrastructure which aims to work and make human life more suitable, comfortable and easier. However, there are still lots of areas such as water controlling where many powers that use manual systems for monitoring as well as controlling the gated dams. As the manual one is less accurate and time-consuming process, this proposed Automation System will permit the end user to observe as well as control the gated dams distantly using PLC device and SCADA software which minimizes the error and time while reducing the cost and increasing the quality of monitoring and controlling with added human safety measures.

The main aim of our paper is to generate electricity by using pressure of wind created by the fast moving vehicle in highways. Wind power has sufficient potential to overcome the demand in energy sector. This demand can be overcome by using vertical axis highway windmill (VAHW). In India only 13.4% of renewable energy sources utilized, remaining energy is get wasted. The introducing a new unique method of VAHW, wind energy was effectively used. By using pressure of air which is much higher in the central part of highway, vertical blades of windmill will rotate. Generator will produce electricity by using rotation of blades. The use of magnetic levitation technique, the efficiency of the project is get improved because it reduces the frictional losses and increase the rotational speed. Maglev wind turbine is able to rotate at minimum wind speed i.e, at 1.5 m/s. Which is not possible in conventional one. So we can get better results and the utilization of wind energy is get increased.

This abstract explores the technique of employing a proxy server as a means to mitigate the impact of DDoS attacks. By introducing a buffer node between clients and servers, the proxy server acts as an intermediary, filtering and inspecting incoming traffic to identify and discard malicious requests while allowing legitimate traffic to reach the server. Additionally, the proxy server can enforce rate limiting measures to control traffic flow, preventing overwhelming volumes of requests from reaching the server. Although this approach can enhance DDoS protection, it is important to consider potential latency implications and the possibility of determined attackers bypassing the proxy server. Thus, a comprehensive DDoS mitigation strategy involves multiple layers of defense, including networkbased and application-based defenses. By leveraging the proxy server technique alongside other measures, organizations can bolster their network defenses, fortify their resilience against DDoS attacks, and ensure uninterrupted availability of their services.
