The main aim of this project is to monitor and record the power meter reading and send the information to the mobile by using GSM technology about the power meter reading .

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. When ever 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.
Section 1:

In section 2 (electricity board section) this section is placed in electricity board. Here we are using the lpc2148 controller so internally rtc is there in this controller. By using this rtc hourly once we are sending the request sms to the section 1 to get the information about power meter reading. Then it will calculate the amount and sends that information to the consumer mobile (sms) through gsm modem. Here we are maintaining the last month details in a data base (in eeprom).

Section 2:

 Every system is automated in order to face new challenges in the present day situation. Automated systems have less manual operations, so that the flexibility, reliabilities are high and accurate. Hence every field prefers automated control systems. Especially in the field of electronics automated systems are doing better performance.  

Probably the most useful thing to know about the global system for mobile communication is that it is an international standard. If you travel in parts of world, GSM is only type of cellular service available. Instead of analog services, GSM was developed as a digital system using TDMA technology.
