Energy Meter Reading Over Internet

e conventional energy meter reading system may cause low accuracy and low efficiency. This project, energy meter reading over internet facilitates the display of units consumed and cost over the internet (in the form of chart and gauge).


The project block diagram is shown in the above figure which consists of various blocks such as microcontroller, energy meter, LDR, load, LCD display, GSM modem, and power supply block. The digital energy meter used in this project consists of blinking LED (for 1unit it flashes 3200 times) which is interfaced with 8051 microcontroller through LDR. Thus, the LDR generates an interrupt for every LED blink and is fed to microcontroller. The microcontroller takes the reading and displays the same over LCD interfaced with microcontroller.
