Realtime energy meter reading using GSM

[Prab X]

hi guys, I m doing a project on GSM BASED ENERGY METER READING. I have to display energy meter reading on LCD and Send this reading to the user through SMS. this SMS can be send after every 50 units. This project also includes a EEPROM memory to store the data after switching off the microcontroller module. The user also can send a sms to the energy meter to get the status of the current meter reading.

the user also can get the status of no of loads connected to the meter, their status(ON/OFF) by sending a sms and also to switch on/off the loads.

i don't know how to display energy meter reading on LCD and send it to USER by SMS. Guys, Please help me in my project.

I m attaching the block diagram of my project.

Hi Prab,

Which microcontroller are you using?

[Prab X]

I m using AT89C51 microcontroller and Keil uVision Compiler

[hardik]

i can help you for tarnsfering message  from contorller unit to customer mobile and also from customer mobile to controlling unit.

you have to design module for reading data from energy meter into controller.

thanks for your interest in my project. I developed a code which will count 1000 pulses and increment unit =unit+1. i have not used external interrupt (INT0 PIN3.2 of AT89C51). Please developed this code using EXT INTERRUPT (INT0) & also help me to send the LCD display content by SMS to user after every 100 units consumed.

 

MY Code:

 

#include<reg51.h>

#define LCD P2

 

unsigned int Count,Unit,d1,d2,d3,d4,x1,x2,x3,d5,d6,d7,d8,x4,x5,x6,x7;

 

sbit rs = P1^0;

sbit rw = P1^1;

sbit en = P1^2;

sbit Pulse = P1^3;

hiiii

i am also working on this project.i want a help for programming a microcontroller for gsm module and including display on lcd

 

[rahul]

hey I am also working on this project.. but I am stuck at the optocoupler part.. the voltage levels from the energy meter are faint. I measured them across the LED

[Prab X]

 I want to send “UNITS:0009” displaying on lcd to a mobile via sms. Please some code for me.

[raviranjan singh]

 

hello freinds..

i am doing the same project with using AT89s52 (8051)

i got stuck on some problem,

please help me as soon as possible..

 

 

is opto coupler is neccesary to use/ can be use relay for the same use.

how to get output from energy meter to microcontroller.

i am going through ine website….is it right

 

 

 

 

 

please freinds send me the proggramme in c to my email id is

hi prab, am really impressed by the amount of effort you already put into this project and just coincidentally am doing same as my final year project in school. but in my case am using the analogue meter so am not using any optocopler,as using an infrared sensor which will read as the electromechanical blade makes is rotation reading the amount of energy used by the load,am also using the AT89S52 8051 micro controller. please i would like to work with you in actualizing this work, i got my GSM MODEM and other components and i already interfaced my infrared sensor to the meter. but am having troubles with my circuit, please could help me so we share materials and idea. i will go through your program now and see how it works with the LCD interfacing, thanks. u can reach me at  [email protected]

Hi,

 

This is really surprising that many people are working on this simple project.

 

I had developed this for my hobby. I would like to ask all of you, how many of you have included measurement of power factor?

 

This is one of the most important parameter in the measurement of power as power=voltage*current*power factor.

 

Reply as soon as possible. 

[Tunde George]

 very well i was finally able to justify my design. as d implementation was realy intresting though i finally used PIC in my design with a current sensor.

[Rajib Saha]

use ldr to count the number of pulses…
