Piezoelectric Sensor:

A piezoelectric sensor is a device that uses the piezoelectric effect to measure pressure, acceleration, strain or force by converting them to an electrical signal. Other than that,piezoelectric sensor have  different type such as ceramic piezoelectric sensor and quartz crystal piezo sensor. But on this project will be use ceramic piezo sensor.  This project an array of 10 piezoelectric sensors is used for generation of power.

Lead Acid Battery:

Battery (electricity), a variety of electrochemical cells for electricity storage, either independently connected or exclusively connected and housed in a single unit. An electrical battery is a blend of at least one electrochemical cells, used to change stored chemical energy into electrical energy.

ADC (analog digital converter):

An analog-to-digital converter (abbreviated ADC, A/D or A to D) is a device that converts a continuous quantity to a discrete time digital representation. An ADC may also provide an isolated measurement. The reverse operation is performed by a digital-to-analog converter (DAC). Typically, an ADC is an electronic device that converts an input analog voltage or current to a digital number proportional to the magnitude of the voltage or current. However, some non-electronic or only partially electronic devices, such as rotary encoders, can also be considered ADCs.

Microcontroller:

This project uses the AT89S52 Microcontroller and Features of this microcontroller includes 8K bytes ROM, 256 bytes RAM 3) 3 Timers, 32 I/O pins, one Serial port, 8 Interrupt sources Here we are using AT89S52microcontroller to display the amount of battery get charged when we place our footstep on piezoelectric sensor.

Load:

Load on this project it mean output after the battery already charge and test the project using load. Load on this project can be use to charge phone, small fan and also can use a lamp or emergency lamp.
