GENERATION OF ELECTRICITY FROM NOISE USING BLOCK CHAIN

Abstract - The increasing global demand for energy, coupled with the rapid depletion of fossil fuels, necessitates the exploration of alternative, renewable energy sources. One such unconventional source is ambient noise—an often-overlooked by product of urbanization. This project investigates the feasibility of converting environmental noise into electrical energy using piezoelectric sensors. Sound-induced vibrations generate pressure waves, which are transformed into electrical signals by the sensor. These signals are then rectified, filtered, and stored in a lithium-ion battery. An ESP8266 microcontroller is employed to monitor sound levels and transmit real-time decibel data to a cloud-based application (“ThingSpeak”) for noise pollution analysis. This dual-purpose system not only promotes sustainable energy generation but also enables continuous monitoring of noise pollution. Cost- effective and environmentally friendly, the proposed device is well-suited for deployment in high-noise areas such as airports, industrial zones, and traffic intersections, contributing to smarter and greener urban environments.
