 In the early phase of household technology, delivery of electricity is
completely depended on traditional energy meters.
 These meters play a key role in measuring the consumption of electrical
energy in individual households.
 The usage of these meters has been slowly declining with the improvement
in technology as fast changes has been made to encounter the problems
occurred by the traditional meters.
 The major problem arises when habitants are unaware of their daily
behavior. Monthly feedback given to the consumers is not sufficient as the
consumers will not have knowledge on how much energy does the
individual appliances consume.
 To overcome the problems of traditional electricity meters, electronic meter
or static energy meter comes in picture. Now a day’s, technology is
developing rapidly .
 Electrical energy is universally accepted as an essential commodity for
human beings.

 The Microcontroller based “Talking Energy Meter” mainly aims at the
middle class and the lower class family to bring their electricity bill down
with the help of the power consumption alert system.
 It benefits the government as it is helps in reducing the power consumption
and succeeding can reduce the unusual power usage. Energy meters being
deployed at homes are used for reading the power that is being consumed.
 Each consumer may fix a customized threshold value (unit). If the value
reaches above the threshold, it will alert to the consumer by voice module.
 This system may install at any place where the energy consumption should
be regularly monitored and controlled.
 The consumers can fix their own threshold budget values and can be easily
customized based on their requirements.
 It also alerts the user if someone tries to steal the electricity from meter by
using IR sensor and cut the line and inform the Electricity Board by mobile
application.

 In Power Consumption Alert System [2], they design a circuit
which helps the consumer in taking care of the electrical
energy consumption, to make the consumer aware and to
control the excess power consumption.
 This system will inform the consumer about their usage rate
via SMS.
 Once the maximum threshold value is reached, power is cut
off with a prior notification to the consumer. Due to this,
customer feels inconveniency in emergency condition. This
system gives the alert to the consumer via SMS only.


 a) Manual Interference
Traditional meter reading of electricity consumption is done my
human operator by visiting one place to another in every month. This
takes more time to collect the data from each and every user and also
requires more human operator. Due to human interference, error may
occur in reading and results error in billing too.
 b) Electricity usage is not monitored
There is no knowledge of electricity usage because in existing
system only monthly bill comes so consumers not get aware about their
daily usage
 c) No Provision for energy stealing
In previous meter, if energy gets theft by the other people, owner
not gets information about the stealing of their energy meter. And
owner get suffer from this.

Proposed System
 In proposed system, all the drawbacks of
existing system are overcome.
 Talking Energy Meter based on
microcontroller is design to give voice alert
and monitor the energy usage.
 Voice can be in any language so that it easy
to understand for common people. It is more
convenient to physically disabled people.

 The purpose behind this system is to design a circuit which aware the
consumer about their energy usage by giving the voice alert when
consumed energy get exceeds the threshold limit which is set by the
user according to their requirement.
 An AC source is given to the electric energy meter and from this; the
load is connected to the meter via a relay switch.
 The fourth LED of the energy meter is given to one of the digital pins
of microcontroller ATMEGA 328 at port C as shown in fig. 4.
 The microcontroller is connected to the voice module and the GSM
module. The GSM module is used to send and receive messages via a
mobile network to give daily alerts.
 The energy values once taken from the energy meter are digitized and
processed with the help of a microcontroller ATMEGA 328.
 The billing of the corresponding energy usage is determined and per
unit rate of consumption is set at the time of programming.

 The threshold unit value is set for which the consumption
level increase is notified to the user. And the user can
change that threshold limit according to the requirement by
using dome switch.
 A relay switch is connected with the microcontroller and the
load which is used to cut the supply if someone tries to steal
the electricity. It is used as protection purpose.
 Voice Module is used to give the alert when consumption of
units exceeds the set limit by user.
 As soon as the limit exceeds, the voice alert occur and SMS
get send on registered mobile number.

 The project “Design a Talking Energy Meter based on
Microcontroller” is design such that whenever the
usage of energy exceeds the threshold value which is
set by user, it announces an alert message which was
already predefined in the voice circuit.
 The SMS of monthly billing status is also sends on
user’s mobile number which is mentioned in program.
The snapshot of SMS is shown in below fig.

Energy Usage Status

 This energy meter alerts the user incase of over usage of
electricity.
 Announces the power supply status. This is very useful for
blind people too.
 Announces about the bill payments.
 This can be customized to any language. As we need to
store the voice message before using this.
 Very helpful for illiterate people. They can know the bill
and meter reading- using announcement without taking help
from literates.
 Easy of design and less cost compared to analog meter.

 Interfacing energy meter to Micro Controller is
sensitive.

 This system can be practically implemented in real time
where there is a limitation on energy utilization.

 The Talking Energy Meter based on Microcontroller is used to alert the
user whenever the usage of energy exceeds the threshold value which
can be set by user by using dome switch, it announces a voice message
which is already predefined in the voice module.
 This helps in saving electricity and also keeping the electricity bills under
limits.
 It not only benefits the consumer, but also benefits the government as it
is capable of reducing the power consumption and subsequently can
reduce the unusual power usage.
 By using this meter, customer can manage their energy consumption.
 A small module consisting of the Microcontroller ATMEGA 328, Voice
Module aPR33A3, IR Sensor, GSM Module and RTC DS 1307 can be
installed with energy meter to make the electricity consumption smarter.
 In this system, the use of GSM and voice module provides numerous
advantages over the methods that have been previously used.
