Abstract— In this paper, we propose a system which measure
the current consumption unit through IR sensor unit. The IR
transmitter is placed in the rotating unit of the EB meter. The
receiver photo diode is placed in a certain place which is used to
find no of rotation. By getting the number of rotation we get the
current consumption. After getting the current consumption
the ARM processor will reduce the unit given for specific user.
The unit here is taken as numeric value. If the unit is reduced to
minimum value it will intimate the user through alarm and
LCD unit. If the user wants to add more units for him, he has to
send a message to EB section. From the EB section the required
value will be sent to the ARM controller through GSM modem.
From the obtained value the ARM will increment the unit in
the memory. Thus recharge process is done quickly with less
manual interactions. Our system may be applied in Industrial
control, medical system and access control.
Keywords— Communication, GSM modem, LCD, Energy
meter.
I. INTRODUCTION
N A wireless local area network (WLAN) links two or more
devices using some wireless distribution method and usually
providing a connection through an access point to the wider
Internet. This gives users the mobility to move around within a
local coverage area and still be connected to the network. By
using Wireless Body Area Network the users links the devices
through their body and nearby devices. From the recent
development in low power Wireless Sensor nodes in WBAN,
the applications are categorized into two as Medical and Non
medical. In medical applications the vital data’s are transferred
through this wireless network which is used in prevent the
occurrence and treat the diseases.
II. LITERATURE SURVEY
Subhashis Maitra (Oct 2008) In this paper, a new concept of
energy meter will be discussed, where maximum demand of
energy of a consumer will be indicated in the meter used by the
consumer. After exceeding the maximum demand, the meter
and hence the connection will automaticallybe disconnected by
an embedded system inserted in the meter itself. According to
the maximum demand, the consumer will purchase a cash-card
of amount depending on the consumption of energy and after
the full consumption, the consumer again has to purchase
another cash-card or recharge the same and thus the hassle
related to go to the billing office, to stand in a long queue and to
submit the bill, can be avoided. Also this system helps to
eliminate the draw backs of billing management system, such
as to take the reading from the meter, to create the bill, to print
the bill, to send the bill to the proper address and to collect the
amount for the bill [6].

that the development of the GSM network as a low cost, global
carrier of digital telecommunications signals provides exciting
opportunities for novel applications such as the handling of
power system metering and load management telemetry. As the
use of GSM for telephony becomes more widespread, it is
inevitable that costs will be driven lower, and it is also
inevitable that this medium for the transfer of telemetry data

In this paper, the authors discuss the way to adopt the cost
effective GPRS applications. Although there have been lots of
theories and concepts on the GPRS applications but the real
applications applying to a large network, distributed power
generation or building energy/power distribution monitoring
are limited. The authors focus the application of the GPRS to
this on-line system application and the techniques. A practical
scheme is proposed and its use to real-life system will be
introduced. A practical implementation for an wireless GPRS
on-line Power Quality Monitoring System will be illustrated.
Results and benefit to the end users in some practical
applications will be discussed.[5]

The development of a GSM automatic power meter reading
(GAPMR) system is presented in this paper. The GAPMR
system is consists of GSM digital power meters installed in
every consumer unit and an electricity ebilling system at the
energyprovider side. The GSM digital power meter (GPM) is a
single phase IEC61036 standard compliance digital kWh
power meter with embedded GSM modem which utilize the
GSM network to send its power usage reading using short
messaging system (SMS) back to the energy provider
wirelessly. At the power provider side an ebilling system is
used to manage all received SMS meter reading, compute the
billing cost, update the database, and to publish billing
notification to its respective consumer through SMS, email,
Web portal and printed postage mailing. A working prototype
of the GAPMR system was build to demonstrate the

Power Supply Unit
The supply of 5V DC is given to the system which is
converted from 230V AC supply. Firstly, the step down
transformer will be used here for converting the 230V AC into
12V AC. The microcontroller will support only the DC supply,
so the AC supply will be converted into DC using the bridge
rectifier. The output of the rectifier will have ripples so we are
using the 2200uf capacitor for filtering those ripples. The
output from the filter is given to the 7805 voltage regulator
which will convert the 12V DC into 5V DC. The output from
the regulator will be filtered using the 1000uf capacitor, so the
pure 5V DC is getting as the output from the power supply unit.
Here we are using the PIC microcontroller which will be
capable of getting the supply of 5V DC so we have to convert
the 230V AC supply into 5V DC supply.
Micro controller unit
In the micro controller unit we are going to use ARM
LPC2129 microcontroller which is used to sense the values
from the sensors and will transfer to the monitoring section

ARCHITECTURAL OVERVIEW
The LPC2119/2129/2194/2292/2294 consists of an
ARM7TDMI-S CPU with emulation support, the ARM7 Local
Bus for interface to on-chip memory controllers, the AMBA
Advanced High-performance Bus (AHB) for interface to the

compatible superset of ARM’s AMBA Advanced Peripheral
Bus) for connection to on-chip peripheral functions. The
LPC2119/2129/2194/2292/2294 configures the
ARM7TDMI-S processor in little-endian byte order.
AHB peripherals are allocated a 2 megabyte range of addresses
at the very top of the 4 gigabyte ARM memory space. Each
AHB peripheral is allocated a 16 kilobyte address space within
the AHB address space.LPC2119/2129/2194/2292/2294
peripheral functions (other than the interrupt controller) are
connected to the VPB bus. The AHB to VPB bridge interfaces
the VPB bus to the AHB bus. VPB peripherals are also
allocated a 2 megabyte range of addresses, beginning at the 3.5
gigabyte address point. Each VPB peripheral is allocated a 16
kilobyte address space within the VPB address space
The connection of on-chip peripherals to device pins is
controlled by a Pin Connection Block. This must be configured
by software to fit specific application requirements for the use
of peripheral functions and pins.LCD Moniror is given in

V. RESULTS AND DISCUSSION
In our Approach we design a system with IR sensor
and GSM technology. Instead of this we can use SPI metering
IC which will provide more parameters. By using three phase
IC MCP3909 we can extend to the three phase supply.
VI. CONCLUSION
In this paper,Various electronic meters have been developed
and are still being developed. However the use of GSM in this
particular system provides numerous advantages over methods
that have been previously used. Data transmission is charged at
standard SMS rates, thus the charges are not based on the
duration of data transmission. The cost efficient transmission
of readings ensures that power consumption values can be
transmitted more frequently to a remote station. The
implications of being able to transmit readings more often are
that energy utilities will be able to generate timely bills, better
understand energy demand patterns, manage meter failures
more efficiently and manage fraud better.
