3. Statement of Problem
DVR & Dr. HS MIC College Of Technology 3
• The main aim of the Programmable energy meter project is to estimate energy consumed by load with the
help of ATmega and calculates the cost. Energy meter gives pulses which will be counted and displayed on
LCD.
• These pulses occur depending on energy consumed .GSM to send SMS on amount of energy consumed. 12V
Transformer to give power supply to the system.
• The system switches the loads ON/OFF Depending on user commands received through SMS. The system
also includes a feature in which user can specify the number of days for which the user wants to retrieve the
consumed and the estimated cost for the specified days.

4. Abstract
DVR & Dr. HS MIC College Of Technology 4
• Electricity Energy Meter is a good concept in which you can recharge its balance, like we do in our mobile
phones. In this project we are building an automated system by using 8051 microcontroller and GSM module.
The main objective of the project is to develop an energy meter that informs the consumer the exact
consumption and billing that the load consumes through SMS.
• For this project, we have taken a standard electronic energy meter. The blinking LED as seen on the front panel
is directly proportional to the power consumed. More the power drawn faster becomes the LED blinking
pulses. One sensor is placed above such blinking LED to derive the real time units consumed whose output
goes to an 8051 microcontroller.

5. Introduction
• An embedded system is a combination of software and hardware to perform a dedicated task. Some of the main
devices used in embedded products are microprocessors and micro-controllers. An embedded system is a
computer system designed to perform one or more dedicated functions often with real-time computing
constraints.
• It is embedded as a part of a complete device often including hardware and mechanical parts. By contrast ,a
general-purpose computer ,such as personal computer (PC), is designed to be flexible and to meet a wide range
of end-user needs. Embedded systems control many devices which are in common use today.

Arduino Uno
• Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output 6 analog inputs,
a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button. It contains
everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it
with a AC-to-DC adapter or battery to get started.
Specifications:
• Microcontroller : ATmega328
• Operating Voltage : 5V
• Input Voltage (recommended) : 7-12V
• Input Voltage (limits) : 6-20V
• Digital I/O Pins : 14

Energy Meter
• An electronic energy meter or electricity meter is an instrument used to calculate the total energy consumed by a
commercial office, home, or electronic device.
• The meter automatically tracks your energy usage, and sends that information to your energy supplier .
• Energy meter is easy to monitor your energy usage and spending using in home display

GSM Modem
• A GSM modem is a specialized type of modem which accepts a SIM card, and operates over a subscription to a
mobile operator, just like a mobile phone.
• When a GSM modem is connected to a computer, this allows the computer to use the GSM modem to communicate
over the mobile network.

LCD(Liquid Crystal Display)
• LCD (Liquid Crystal Display) is a type of flat panel display which uses liquid crystals in its primary form of
operation. LEDs have a large and varying set of use cases for consumers and businesses, as they can be commonly
found in smartphones, televisions, computer monitors and instrument panels.

Capacitor
• A capacitor is an electronic device that stores electrical energy in
an electric field, accumulating electric charges on two closely
spaced surfaces that are insulated from each other. It is a passive
electronic component with two terminals.
Relay
• A relay is an electrically operated switch. It consists of a set of
input terminals for a single or multiple control signals, and a set of
operating contact terminals.
