The main objective of this project is to develop a GSM based energy meter reading system
and load control through Messaging. Electricity department sends employees to
take meter reading every month, which is an expensive and time
consuming job. The proposed project provides a convenient and efficient
method to avoid this problem.
The electricity department and the user can get the readings of the
energy meter of consumers via SMS. The loads can also be controlled by
the user of this system via SMS using this project.
A microcontroller input is effectively interfaced to a digital energy
meter that takes the reading from the energy meter and displays the
same on an LCD. The reading of the energy meter is also sent to the
control room by an SMS via SIM loaded GSM modem.
This GSM modem can also receive commands from the cell phone to
control the owner’s electrical loads. It uses a standard digital energy
meter that delivers output pulses to the microcontroller to perform
counting for necessary action. On receiving command it can switch ON/OFF
Further this project can be interfaced with a non volatile memory IC
like EEPROM along with a keypad so that the user the change the mobile
number as per the requirement.
