The Overloaded Van Indicator project uses an Arduino, a force sensor, and an LCD screen to prevent overloading. It shows the load's weight in real-time and stops the van if it’s too heavy. This simple system helps keep the van safe, prevents damage, and ensures it follows load rules.

This Arduino-based non-biodegradable waste separator uses an ultrasonic sensor, servo motors, and a shaft which is attached to the DC motor to detect and sort waste. By directing non-biodegradable items into designated bins, it promotes efficient recycling and waste management, addressing environmental pollution. This innovative solution enhances sustainability and reduces landfill waste.

The Solar-Powered River Cleaning Boat is an innovative project designed to tackle the persistent issue of water pollution in rivers and other water bodies. This project involves creating a solar-powered river cleaning boat designed to remove waste from water bodies efficiently. The boat utilizes a solar panel to charge a rechargeable battery, which powers BO geared motors. These motors drive the boat and its cleaning mechanism, constructed from corrugated sheet, cans, and jute material, to collect and remove debris from the river.

This project focuses on creating an automatic filter mechanism to improve indoor air quality by reducing smoke levels. The system uses a DC motor attached to a toy fan, which functions as an exhaust fan. When the smoke level in the room increases beyond a certain threshold, the fan activates to expel the smoke and improve air quality. This basic STEM project combines elements of electronics and environmental science.

This innovative solution integrates automated water level management with water conservation. By preventing waterlogging and optimizing water use, it addresses agricultural inefficiencies, reduces water waste, and maintains groundwater levels, thus benefiting farmers and communities reliant on sustainable water resources.
