@jayanth.devarayanadurga, thanks for ur help. Can i use at89s52 mcu ? reading after 800 pulses will be 0.2496. my gsm module datasheet,go to link https://www.uploadmb.com/dw.php?id=1362327200
what about the displaying reading on lcd?
@jayanth.devarayanadurga,thanks for your questions. i don't have any idea what to do if these conditions occur during real time operation. can u help in this matter? please also help me in programming to send the meter reading via sms. i don't how to send the readings via sms...... :-(
The digital power meter was set to display six digits with one decimal point reading in kWh unit and a meter constant of 800 impulse per kWh. The digital power meter has an optocouple meant to couple the impulse count to any external electronic circuitry without direct contact to the digital...
@jayanth.devarayanadurga, yeah !units has to be stored on eeprom, and has to be checked whether old reading is equal to or mor than 100 units before sending sms to user. can u modify my program given above to add these things.

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...
sir,im using at89c51 and keil compiler. i hv interfaced energy meters' Cal led with optocoupler mct2e then output from mct2e to microcontroller. but i don't how to count the pulses and display the units on lcd. please help me in coding.
