This was my first attempt in the field of Embedded Electronics, so kindly have a look at my brief presentation that I have made about my work and experience in this field for the very first time.

1. Open Power Monitor
 Well this my attempt to create my own Open Power
Monitor System.
 The main purpose of the project is to create a power
monitoring system that would send electricity usage
of a particular user to a web server

2. Cooking a dinner, heating a house, lighting a
street, keeping a hospital open, running a
factory – all these require energy. Energy is
thus at the heart of everybody's quality
of life and a crucial factor for economic
competitiveness and employment. But global
population and energy needs increase hand-
in-hand and the current fossil-fuel based
energy system is not sustainable as it
contributes substantially to climate change
and depends heavily on imports from very few
countries. Answers to the dual challenge of
satisfying increasing energy needs and
combating climate change at the same time
are urgently needed and energy research can
play an essential role. India can not move
towards sustainable growth without radical
changes in the way it generates and uses
energy.

3. Energy Crisis in India
An energy crisis is any great bottleneck (or price rise) in the supply
of energy resources to an economy.
Energy is as important as fuel as it not only powers up our
home or drives cars for us, but it is the back bone of
nation’s economy.

4. Why Energy Monitoring System?
 When energy consumption
becomes available for viewing and
analysis, people tend to find natural
ways to reduce their own consumption
 It alerts them to situations where
they may be acting in an
unintentionally wasteful manner. In
households, this reduction can be as
much as 7% when the power meter is
placed in a visible location within the
house.
 That is the benefit a single meter
can do, imagine an entire system
dedicated exclusively to energy
monitoring and analysis.

6. Designing Part
 Getting Started
 First Part of my device :- CURRENT
TRANSFORMER

7. DIGITAL CLAM(CT) METER
Current Transformer

8. Current Transformer
 A current transformer (CT) is used for
measurement of alternating electric currents.
 A current transformer produces a reduced current
accurately proportional to the current in the circuit,
which can be conveniently connected to measuring
and recording instruments.

9. Before we proceed further ….
 The readings which CT will detect will be analog in
nature and I need to convert that into digital data so
that I can transfer it to COM.

10. Difference between Analog & Digital?!
Analog signal is a continuous signal which
represents physical measurements.
Digital signals are discrete time signals
generated by digital modulation.
Uses continuous range of values to
represent information
Uses discrete or discontinuous values to
represent information
Analog technology is cheaper but there
is a limitation of size of data that can be
transmitted at a given time.
Digital technology has revolutionized
the way most of the equipments work. Data
is converted into binary code and then
reassembled back into original form at
reception point

11. Now comes Arduino NG ATMEGA8 into action, this is probably
one of the initial model of Arduino family, and it’s quite OLD
SCHOOL, but very effective. As you must be aware that
Arduino comes with built in A2D converter. So I coded my
program into the Arduino using GUI based program for
Arduino Embeddedment that comes in SYNAPTIC PACAKGE
MANAGER IN UBUNTU.

12. So I added few more components, thanks to openpowermonitor.org
that provided me a bit of guidance! And voila my project was ready.
Just for my convenience I added an LED 4 bit display!

14. Not over yet!!
 Since I have a serial to USB converter, in my main
system, I am writing a python script that would
enable data to be fetched from COM port and then I
can send that data to a web-server.
 Moreover the work is still in progress
 Any help regarding this is welcome

15. Thank You
 Code and detailed wiki will be uploaded on GitHub
very soon
