The world is moving towards clean energy sources, and only renewable energy can fulfill these needs. One of the cleanest sources of renewable energy is the PV panel. This paper is based on the MPPT Controller, which works on different constant voltage algorithms. Solar PV-based power plants can also provide electricity at night, and this type of PV-based power plant is known as a hybrid power plant. For hybrid plants, batteries are used to store the energy during the daytime and deliver this stored energy at night. The purpose of this paper is to represent a simulation of a solar power plant based on an MPPT controller which can provide power in the daytime and at night. The system can provide uninterrupted power without any problem. Segments of the simulation were PV array, MPPT controller, Buck Converter, Battery controller, Display, Inverter, etc. The waveform of Irradiance, 3 phase modified sine wave, is plotted to observe. Rather than this whole project’s efficiency and productivity were simulated in RETscreen.

A microcontroller-based ventilator was developed including a health monitoring system featuring a Wi-Fi-based notifier. A pressure-controlled ventilator was included, and an AMBU bag was used for controlling the breath length and pressure. In monitoring the system, Oxygen Saturation, body temperature, and Heart Beat rate were measured using specific modules. The measured data were shown on the display, and for critical conditions, the system alerted using Wi-Fi technology. The ventilator responded according to the data and changed the pressure of the Air Breather Bag using motors. A non-invasive ventilation mask was used for ventilating the patient’s lung and a manual control mechanism was used for emergency. There was an option for attaching an oxygen cylinder/concentrator. A battery was used to power the system.

A frontend-only web application developed using React, React Router DOM, and Tailwind CSS, designed to demonstrate dynamic and responsive user interfaces. The app features multiple navigable pages, interactive components, and state management, all powered by fake/mock data to simulate real-world functionality. It showcases clean UI design, smooth transitions between routes, and responsive layouts optimized for different screen sizes, making it a practical example of a fully functional frontend application without a backend.
