Arduino Based Footstep Power Generation with Battery Level Indicator

Abstract

The footstep power generator is the technique by which electricity is generated from the mechanical energy created during the process of walking. The system makes use of piezoelectric sensors fitted under a surface which produces voltage upon the application of force. The generated energy in its raw state is alternating and can be converted to DC through a rectifier.

An essential drawback in present systems is the absence of any system of energy monitoring. Most devices show the voltage which does not necessarily tell anything about the battery life. In this project, an Arduino Uno which is based on ATmega328 chip will be used to continuously monitor the voltage level in the battery and the percentage of charge present. The value obtained is shown on the 16×2 LCD screen. It gives better efficiency, usability and safety to the system.
