The
main aim of this project is to read the value from the energy meter of
different flats or offices in a apartment and pass this read data to the
main system using Zigbee and from there to user mobile. This digital
meter, that reads the number of units, is actually a digital meter. This
energy meter will be interfaced with the microcontroller. The
microcontroller reads the data from the energy meter and passes this
data to the GSM modem via Zigbee technology. This data is also displayed
on the LCD.
The
modem provides the communication interface. It transports device
protocols transparently over the network through a serial interface.
The
GSM modem is a wireless modem that works with a GSM wireless network. A
wireless modem behaves like a dial-up modem. The main difference
between them is that a dial-up modem sends and receives data through a
fixed telephone line while a wireless modem sends and receives data
through radio waves. This modem sends the data, which is read from the
energy meter by the microcontroller, to the user mobile.
