ABSTRACT–
Noise Pollution is an everyday reality of a developing economy. This project is designed to convert the decibel levels of the unwanted noise to useful energy, serving 2 purposes: Working as a sustainable energy source that stores the electrical energy for future use and also indicating the noise levels in an area using a microphone and Arduino. The sound vibrations cause waves of pressure which get translated into electrical energy with the help of piezoelectric sensor. This energy passes through a bridge rectifier and a capacitor and is finally stored in a Lithium ion battery for future use while also displaying the decibel levels (dB) and verifying it on an app called “Sound Meter”, achieved with the help of Arduino. This is a sustainable source of energy and is highly cost effective making the product affordable to the masses.
