IoT Footstep Power Generator Science Project

ESP32 Smart Piezo Footstep Power Generator Project Kit

The ESP32 Smart Piezo Footstep Power Generator Project Kit is an innovative renewable energy science project designed to demonstrate how electrical energy can be generated from mechanical force such as footsteps or vehicle pressure. This educational project uses piezoelectric technology to convert pressure into electrical energy, making it an excellent demonstration model for science fairs, STEM education, and engineering exhibitions.

This IoT-enabled project is built around the powerful ESP32 microcontroller, allowing users to monitor generated energy data remotely through cloud-based mobile applications. The project utilizes three 35mm prewired piezo disc sensors that generate small amounts of electricity whenever force is applied. The generated energy level is displayed locally on a 16x2 LCD display with an I2C interface and can also be viewed remotely using internet connectivity.

The Footstep Power Generator Science Project available from Biggan Project is specially designed for students, teachers, and hobbyists in Bangladesh who want to explore renewable energy concepts practically. This project is widely used in science fairs across BD to demonstrate sustainable energy generation methods and IoT-based monitoring systems. Students can easily understand the principles of energy harvesting, piezoelectricity, cloud connectivity, and embedded system design through this project.

The project operates using two 18650 rechargeable batteries connected through a dual battery holder. Since the battery output voltage is approximately 7.4V, an LM2596 buck converter is used to safely step down the voltage to 5V for powering the ESP32 and LCD display. Users should ensure correct polarity while connecting the LM2596 module because reverse polarity may damage the converter.
