Prepaid Energy Meter using GSM
This project is based on VTU syllabus. The proposed system is based on ATMEL 89S52 µcontroller which is in our syllabus. For doing this project we use some of the software like ❖ Embedded C for programming the application software to the microcontroller. ❖ Protel schematic software is used for designing the circuit diagram for this project. ❖ Express PCB software is used for designing the PCB for this project. (Since PCB making is a big process and involves lot of machineries which are expensive, we are going to outsource this to the manufacturer.)
Every month we can see a person standing in front of our house from Electricity board or water Board whose duty is to read the energy meter/water meter and handover the bills (electric or water) to the owner of that house . This is nothing but meter reading. According to that reading we have to pay the bills. The main drawback of this system is that person has to go area by area and he has to read the meter of every house and handover the bills. The Electricity board and Water authority has to give privileges for these people to do their duty monthly. The thing is, Government will not appoint any particular persons for this duty. The people working in these boards will go on a particular day and do their duty leaving all their pending works. Due to this, their work will be delayed and this is great loss for government. To overcome this drawback we have come up with an idea and this idea will help the government and it will save the time of the employees working in these boards. The aim of the project is to automate the prepaid billing of energy meter and water meter. In this project the front end is User friendly and the employees can work on this software with minimum knowledge of Computers. Employees can read the meter by sitting in the Office. For front end designing Java is used.

This project is useful for billing purpose in Electricity board and in water authority. Instead of going to every house & taking the readings, in this project by just sending an SMS we can receive the readings of the house and we can recharge the electric bill. This system uses Java Basics software, which is designed as the application platform to send or receive SMS using the Modem, then process and stores the data. Java software has two main functions 1) to interact with Modem and read the COM port 2) maintain the database.
In this project the micro controller & the GSM unit is interfaced with the Energy meter/water meter of each house. Every house has a separate number, which is given by the corresponding authority. The GSM unit is fixed in the energy meter/water meter.
The amount of consumption is stored in memory authority as SMS. Using this software we can send the SMS through Modem to that particular number which is assigned by these authorities and wait for the response. On other end the modem will receive the data in the form of a command and informs the controller to do the readings. After the readings the controller will send data to the modem. Modem, in turn sends data to the other end. In the office the GSM unit will receive the data and the Java software will calculate the total consumption. The number assigned by the authorities is Unique. Using GSM we can get the response very fast due to which time is saved. After completion of the pulse the power will cut again consumer wants to send an SMS for recharge. This is due to reduce illegal power using with out paying the money.
