Electricity Generation Road Project Using Piezo Sensor

Smart Piezo Road Power Generator Science Project by Bigyan Project

The Smart Piezo Road Power Generator Project from Bigyan Project is an innovative science project designed to demonstrate real-time electricity generation from road movement, footstep pressure, and vehicle load. This advanced educational model showcases how renewable energy can be harvested from mechanical stress using piezoelectric sensors. The system uses three high-quality 35mm prewired piezo discs to generate electricity whenever pressure is applied. The generated voltage is stored in two 18650 Li-ion rechargeable batteries through a regulated energy conversion circuit. An Arduino Uno R3 microcontroller with an I2C 16x2 LCD display shows real-time voltage output and system status, making it a complete learning tool for students, researchers, and innovators.

This project is perfect for school and college exhibitions, DIY hobbyists, renewable energy demonstrations, and STEM learning labs. It is designed to make science engaging, practical, and interactive while showing the future of smart road systems that can power lights and sensors using movement-based energy harvesting. Bigyan Project proudly presents this as a ready-to-use educational kit for understanding piezoelectric energy conversion.
