gsm based electric meter reading using java with source code

This GSM energy meter is constructed using
the microcontroller, a display, GSM modem and
microchip. In this, meter is designed using embedded
GSM modem and by using existing GSM network to
send wirelessly its energy consumption value as SMS
to energy provider. At the time of sending the
message every time, this data is stored in the nonvolatile
memory (EEPROM). We use RTC module
also with meter to have all recording of usage details
about energy consumption. In the office, the this
GSM unit will receive these collected data and local
software will process on that data and calculate the
total power consumption of each user. The system
design can be discussed as two broad categories,
Hardware implementation and software web portal
design implementation.
