INTRODUCTION. . .

The arduino based energy measurement aims to measure

energy consumption.

The need of providing such data to the user is to reduce

the energy consumption.

POWER. . .

Power is the rate at which energy is generated or consumed.

Real power is the actual energy consumed by the load.

Reactive power is stored in and discharged by inductive loads.

Power quality determines the fitness of electrical power to consumer devices.

Synchronization of voltage, frequency & phase allows electrical systems to function in their intended manner.

Without proper power an electrical device may not operate at all.

ENERGY

The amount of energy used (or supplied)

depends on the power and the time for

which it is used.

Energy=Power*Time

Energy is found in different forms, such as

light, heat, sound, and motion.

COMPONENTS:

ARDUINO (MEGA 2560)

RESISTIVE LOAD

DIODES

POTENTIAL TRANSFORMERS

CURRENT TRANSFORMERS

ABOUT ARDUINO

Arduino is an open-source single-board microcontroller.

It is an electronics prototyping platform based on flexible

and easy to use hardware cum software.

Arduino MEGA 2560 is used in this project.

Arduino Board Mega 2560

PROJECT INFO. . .

In this project power measurement is carried out

using Arduino MEGA.

The input signals are given to arduino analog input

pins and the programming is done in such a way that

power and energy is obtained at the output.

Conclusion

Arduino energy measurement is an advanced method of

determining energy and this method is more

advantageous than other softwares.

Arduino is an open source software and can be

extended by experienced programmers such as C and

C++. Arduino has simple and clear programming

environment.
