AIM OF THE PROJECT
• The project aim design a energy meter monitoring system using
Arduino and GSM. This design eliminates the human
involvement in electricity maintenance.
• This system uses GSM technology for sending the bill to the
user mobile and control the load.
• The status of the project will display on LCD.

Objectives
• The best remedy for this is not the increase in energy production, but the effective use of
available energy. By properly monitoring our energy consumption.
• Consumer can get their energy consumption(KWH) into the mobile in the form of GSM.
• Consumer can control the load through GSM by sending a simple SMS.
• To turn on and off the load using relay switch.
• To achieve this task using Arduino UNO microcontroller.

REGULATED POWER SUPPLY
 Every embedded system requires dc voltage and that that will
be 5v supply
 We are getting 230v, 50 Hz in our house hold applications.
We can be used to operate the home appliances like T.V,
cooler, fan, light’s
 Digital electronic devices need digital supply and we can
get supply from regulated power supply block

Arduino nano
Arduino Nano is based on the ATmega328 SMD chip. It has 14
digital input/output pins (of which 6 can be used as PWM outputs),
8 analog inputs, 1 UARTs (hardware serial ports), a 16 MHz crystal
oscillator, a USB connection, and a reset button.

ADVANTAGES OF MICROCONTROLLER`
 Low cost
 User friendly
 Easily available in market
 We can reprogram it up to 1000 times
 Less power consumption

Digital Energy Meter
Digital Energy Meter gives fixed number of
pulses per KWH.
These pulses are given to microcontroller for
calculating the units consumed.
Microcontroller calculates the power
consumption for each pulse and displays.
The energy meter we are using gives 3200
pulses per KWH.

Energy meter
An energy meter is a device that measures the
amount of electrical energy consumed by
a residence, business, or an electrically powered
device.
Energy is the product of power and time for which
power is used i.e
Energy= power × time
Induction watt hour meter (Energy meter) which
are commonly used measure electrical energy in
KWH (killo watt-hour)

Benefits of Smart Energy meter
Better Accuracy
Low Current Performance
Low voltage performance
Difficult to temper
Digital display

Optocouplers are used for providing optical isolation
between an input source and output load just by using light.
The basic design of an optocoupler consists of an LED that
produces infra-red light and a semiconductor photo-sensitive
device that is used to detect the emitted infra-red beam. The
pulses from the energy meter are converted into digital signals
by using an optocoupler.

Operation:
An opto-isolator contains a source (emitter) of light, almost
always a near infrared light-emitting diode (LED), that converts
electrical input signal into light, a closed optical channel (also
called di electrical channel), and a photo sensor, which detects
incoming light and either generates electric energy directly, or
modulates electric current flowing from an external power supply.

The optocoupler is a device that contains an infra-red LED
and a photo detector (such as a photodiode, phototransistor,
Darlington pair, SCR or triac) combined in one package

RELAY
► Relay is an electromagnetic switch. . It consists of a coil of
wire surrounding a soft iron core, an iron yoke, which
provides a low reluctance path for magnetic flux, a movable
iron armature, and a set, or sets, of contacts; two in the relay
pictured. The armature is hinged to the yoke and
mechanically linked to a moving contact or contacts.
► When an electric current is passed through the coil, the
resulting magnetic field attracts the armature and the
consequent movement of the movable contact or contacts
either makes or breaks a connection with a fixed contact.

Applications of relays
 Control a high-voltage circuit with a low-voltage
signal, as in some types of modems or audio
amplifiers.
 Control a high-current circuit with a low-current
signal, as in the starter solenoid of an automobile.
 Detect and isolate faults on transmission and
distribution lines by opening and closing circuit
breakers (protection relays).

GSM modem
• Global system for mobiles (GSM) is a
globally accepted standard for digital
cellular communication.
• Any GSM phone will have GSM modem
inside.
• Like any other mobile phone we are also
interfacing GSM modem with our
Microcontroller.
• The GSM modem used in the project is
SIM-900 (SIMCOM).

LCD DISPLAY
 A liquid crystal display (LCD) is a thin, flat electronic
visual display that uses the light modulating properties of
liquid crystals.
 Liquid crystal display is very important device in embedded
system. It offers high flexibility to user as he can display the
required data on it.
 These are used in a wide range of applications, including
computer monitors, television, instrument panels, aircraft,
cockpit displays, signage, etc

PIN DESCRIPTION

 LED’s are used as indicator lamps in
many devices, and are increasingly used for lighting.
 LED’s emitted low-intensity red light, but modern
versions are available across the visible, ultraviolet and
infrared wavelengths, with very high brightness.
LED INDICATORS
 Led indicators have a life of at least ten years and consume
90 per cent less power than conventional indicators.
 Depending on the type of the materials (Ga,As,p) led will
gives the output in different colors (red, Yellow, green etc..)
