INTRODUCTION

Energy Harvesting Door is a device created to harvest and store electrical energy from the movement of opening and closing of a door

PROJECT BACKGROUND

PROBLEM STATEMENT

Non–renewable energy is energy which is taken from the sources that are available on the earth in limited quantity and eventually come to extinction. From the movement of the door (open/close), this potential energy can be utilized and transform into other form of energy. 

OBJECTIVES

Design a low cost working prototype that can harvest the energy from the movement of the door that act as “independent electricity supplier” to produce clean and safe energy.

LITERATURE REVIEW / DATA GATHERING

Electromagnetic induction is a process where a conductor placed in a changing magnetic field causes the production of a voltage across the conductor and this in turn, causes an electrical current

http://physics.about.com/od/physicsetoh/g/induction.htm

Electricity is produced by spinning copper between magnets, which produces electrons that move as current through metal (copper) conductors. With the aim of conserve the energy, potential energy is converting to kinetic energy to generate electrical energy in term of alternating current (AC) to direct current (DC).

Name Description

1 Magnet and coil To convert the electrical energy from kinetic energy produce due to the movement of the door. 

2Rechargeable batteries

To store the converted energy inside it. Can be used for other purposes such as light up a bulb, charging mp3 and etc. 

3 Rectifier To convert AC current to DC current. The DC current then will be stored inside the rechargeable batteries.

5 Drive Shaft To transmitting the torque and rotation from the movement of the door to the needle within the magnet and coil.

6 Connection wires To connect the electronic parts within the breadboard.

7 Breadboard To be the main board in constructing the test circuit.

8 Switch To connect or break the electrical circuit.

9 Digital multimeter To measure the voltage level, current flow and resistance in the circuit.

10 Plywood To make a mini door as a prototype and as the container of the breadboard.
