Pioneering Green Technology: Energy Harvesting through Piezo – Speed Breakers

This Paper explores an innovative approach to sustainable energy generation by harnessing the kinetic energy from vehicles. Utilizing Arduino as the central control unit, the system incorporates six piezoelectric sensors embedded in speed breakers to generate electrical energy when vehicles pass over them. The collected energy is used to power automatic street lights and electric vehicle (EV) charging stations, promoting energy efficiency and reducing carbon footprints. To monitor and manage the energy output, the setup integrates LDR sensors for ambient light detection, which controls street light activation. A relay module facilitates the connection to the street lights and EV charging system. The data is transmitted wirelessly via a NodeMCU (ESP8266) to the Ubidots IoT platform, enabling real-time monitoring and analytics. An additional feature includes a wireless circuit coil transmitter and receiver, enhancing the system's versatility. The generated energy can also be utilized to power LED indicators, providing visual cues for system status. This project not only demonstrates the feasibility of piezoelectric energy harvesting but also showcases a scalable solution for smart city infrastructure, contributing to a greener and more sustainable urban environment.
