Solar Piezo Hybrid Power Charging System

Abstract

The use of Renewable resources like the solar energy and various other clean sources of energy has been an increase in demand in the recent years due to their case in availability and low cost. This project demonstrates of people walking over piezo based foot board. The solar panel is used to harness the solar power. It converts the solar power into voltage, which when more than the voltage in the battery is able to charge the battery. The power available through the solar panel is sensed by an Atmega family microcontroller which is displayed on the LCD. Similarly, the power generated through foot step over piezo foot board is shown in LCD. In this case, the foot step count is also displayed on the LCD along with the voltage generated by that particular foot step, in this way one can charge the battery, through solar and foot step energies while simultaneously also monitoring of how much is getting generated with the use of solar piezo hybrid power charging system. The output is also displayed in web page using wifi module to enhance the field of Internet of Things Technology.
