This document describes a prepaid electricity meter project aimed at minimizing power losses in India. The project involves developing an electronic meter that monitors electricity consumption, informs users of usage via SMS, and allows for prepaid payment of bills. When the prepaid balance reaches zero, the meter will automatically cut off power to loads like bulbs. Key components include a microcontroller, LCD display, GSM module, and relays to control loads. The goal is to shift from a postpaid billing system prone to losses to a prepaid system with automatic notifications and cutoffs to reduce theft.

2.  The concept of Electronic Energy meters are
introduced in the power sector to effectively
Monitor the billing faults and minimize the losses
 Prepaid Energy meter is a multipurpose project
which can integrate all the functions like billing and
automatic message response to user

5.  UP is the country’s biggest center for the country’s
most inefficient power sector failures
 The state is also blamed for overdrawing electricity
from the national grid through illegal means
 According to the World Bank estimates, ignoring
bill payement reduces India’s GDP by around 1.5%
(Smith, 2012)

6.  A study by NDTV also concluded that 40% of the
electricity in India is unpaid
 Of all the power generated in the country, around
1/4th is either stolen or lost in transmission
 Level of electricity losses and the economic growth
rate are inversely related.

10.  Making a proper billing system-from shifting post
paying into pre-paying system
 Device would help notify amount of power consumed
 LCD screen displays the power consumed and
remaining balance
 Inform user about prepaid recharge
 Load would cutoff when balance is null

17.  Narrow operating voltage: 1-16V.
 Low current consumption: 3-100mA

18.  Supply voltage; 5V (4.7V – 5.3V) Vcc
 Contrast adjustment; through a variable
resistor

19.  The term GSM usually means the GSM standard and
protocols in the frequency spectrum around
900MHz
 The MS is the physical equipment used by a
subscriber, most often a normal hand-held cellular
telephone
 The BTS comprises the radio transmission and
reception devices, and also manages the signal
processing related to the air interface

20.  This project could also be used for water
usage management
 These projects will help cut technical and
commercial losses and improve collection
efficiency
 It would reduce human efforts
