The main aim of the project is to generate power from renewable energy sources; system makes use of Piezo. The system monitors the voltage coming from the piezo sensor, energy from piezo sensor values displayed on the LCD. The energy from the piezo sensors is used to charge the battery. A piezoelectric sensor is a device that uses the piezoelectric effect, to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix piezo- is Greek for 'press' or 'squeeze'. The main controlling part of the whole system is Micro controller. In this project Piezo plate along with voltage sensor, LCD are interfaced to micro controller section. Micro controller reads the voltage values from the piezo plate and will be display on the LCD The energy from the piezo plate is stored into the rechargeable battery through charging circuit. Battery power is fed as input to the three USB ports through lm2596 voltage regulator which distribute the different powers to the three USBs for fast and slow charging of electric devices.
