ABSTRACT

Now-a-days technology has developed to a large extend. At the same time the need

for systems with automation and high security are preferred. So, by using one of the best

technologies available i.e. GSM we are designing an automatic power meter reading system

for commercial and domestic purposes. Traditional meter reading for electricity consumption

and billing done by human operator from houses to houses and building to building. This

requires huge number of labor operators and long working hour to achieve complete area

reading and billing. Human operator billing are prone to reading errors as sometime the

houses electricity power meter is placed in location where it is not easily accessible . Labor

billing job is sometime also restricted and is slowed down by bad weather conditions. By

using this project we can avoid such problems.

This project is aimed to develop a system to provide security by intimating the

condition in the form of SMS by making use of GSM technology. In this project we have two

sections .

In section 1 For measuring energy consumed by the user we are going to use one

digital energy meter, at the same time as it uses 1unit the count will be displayed in LCD And

that particular data is stored in the EEPROM. Whenever the request sms received. Then, it

will send the consumed number of units (meter reading) information to another section. The

main objective of this project is to design a prepaid energy meter system with the help of

GSM technology. In this project we are using bulbs as a load. On LCD we are going display

No of units consumed in this hour.
