Abstract: —The footstep Power generation and its use is one of the issues. Now-a- days numbers of power sources are present, nonrenewable & renewable, but still we cant overcome our power needs. Among these human population is one of the resources. In this project we are doing generation of power by walking or running. Power can be generated by walking on the stairs. The generated power will be stored and then we can use it for domestic purpose. This system can be installed at homes, schools, colleges, where the people move around the clock. When people walk on the steps or that of platform, power is generated by using weight of person. The control mechanism carries piezoelectric sensor, this mechanical energy applied on the crystal into electrical energy. When there is some vibrations, stress or straining force exert by foot on flat platform. This output is provided to our monitoring circuitry which is micro controller-based circuit that allow user to monitor the voltage and charges a battery, and this power source has many applications. The project model is cost effective and easy to implement.

The "Eco Walk – Harvesting Energy with Every Step using Arduino Uno" project presents an innovative solution to address the increasing demand for sustainable energy sources. In a world grappling with energy needs, this system capitalizes on the often-overlooked potential of human motion, particularly the act of walking or running. By strategically placing piezoelectric sensors on surfaces like stairs and platforms, the system converts mechanical energy generated by individuals' movements into electrical power. This generated electricity is then stored and made available for domestic use. The project's versatility and cost- effectiveness make it a viable option for implementation in various settings where people are in constant motion, offering a promising step toward harnessing clean and renewable energy from our everyday activities.


In 3 March 2013 Tom Jose v [1] had developed a system for electricity generation from footstep .it is Microcontroller based model for generating electricity it can be used anywhere using Piezo electric sensors. This power is generating in ac form so we need rectifier circuit to store the power.

In 4 Oct 2007 U.K Singh and R.H. Middleton [2] has developed a system piezoelectric power scavenging of mechanical vibration energy here they are using same principle. When mechanical force is applied on Piezo sensors it generates power in ac form so we need to store this power in dc form and also, we need booster circuit.

In 2011 Mechatronics (ICOM) 4th International conference by fakhzan, M.N., Muthalif, A.G.A. [3] their using same principle. Example (1) A beam with piezo ceramic patches have been used as a method to harvest energy. (2) A unimorph piezoelectric cantilever beam generates electric current or voltage from the piezoelectric strain effect

In 20 sept 2014 Generation of electric power through Footsteps [5] k.Ramakrishna, Guruswamy Revana and venu Madhav Gopaka International journal of multidisciplinary and current Research. Their using same principle. Example

(1) Diaphragm movement in certain material will cause generation of electric charge. (2) pressure polarizes some crystals, such as quartz.


In existing systems, we are using solar and wind to generate power. These have some disadvantages. Solar will work up to sunset after that we cant generate power as much as we generated will sun. In wind energy we wont get that much wind which is required to generate power all the time.


Electricity has become lifeline for human population. Demand of electricity is increasing day by day. Some technology needs high amount of electrical power to perform various operations. As we know electricity is generated by some sources like water, wind etc. To generate the electricity from these resources, development of big plants or big mills is needed having high maintenance cost. As the use of energy is increases, no of energy resources are generated and wasted. If the wastage of energy is rapidly increases then one day will come at that time we will face totally absence of energy. When was stored the energy then IR sensor detected power transmission to coils and based on LDR sensor LEDs on and RFID reader acts as mobile charger on.

3.LDR Sensor:

An LDR sensor, or Light-Dependent Resistor sensor, is a passive electronic component that exhibits a change in its

electrical resistance in response to variations in incident light intensity. LDRs are typically composed of semiconductor materials that become more conductive as the ambient light level increases and less conductive in low- light conditions. They are widely used in numerous applications, including automatic lighting control, camera exposure control, and light-sensitive alarms. LDR sensors play a crucial role inenabling devices to respond to changes in the surrounding illumination, making them valuable tools for enhancing energy efficiency and automating various processes that rely on light sensitivity.

An IR sensor, or Infrared sensor, is a device that detects and measures infrared radiation in its surroundings. These sensors are commonly used for proximity sensing, object detection, and motion detection applications. IR sensors work by emitting and receiving infrared light. When an object is in proximity or moves within the sensor's field of view, it reflects or emits heat in the form of infrared radiation. The IR sensor then detects this radiation and translates it into an electrical signal, triggering a response or providing data about the object's presence or movement.IR sensors are found in a wide range of devices, including security systems, automated appliances, and remote controls, making them essential for various sensing and control applications.

A relay is an electromechanical switch used to control the flow of electrical current in a circuit. It operates by using a small electrical signal to activate an electromagnet, which in turn, mechanically switches a larger electrical load on or off. Relays are essential components in various applications, such as automation, electrical control systems, and safety circuits. They allow low-power electronic devices, like microcontrollers, to control high-power devices such as motors, heaters, and lights. Relays serve as a crucial interface between digital and high-power electrical systems, enabling the automation and remote control of numerous processes and devices across different industries.

A rechargeable battery is an energy storage device that can be charged again after being discharged by applying DC current to its terminals. Rechargeable batteries allow for multiple usages from a cell, reducing waste and generally providing a better long-term investment in terms of dollars spent for usable device time. This is true even factoring in the higher purchase price of rechargeable and the requirement charger. A rechargeable battery is generally a more sensible and sustainable replacement to one-time use batteries, which generate current through a chemical reaction in which a reactive anode is consumed. The anode in a rechargeable battery gets consumed as well but at a slower rate, allowing for many charges and discharges.
