This is project is mainly concentrate on collecting digital energy meter data from any where in the world and is divided into two parts one is called transmitter end and the other is called receiver end.
At the transmitter end digital energy data will be continuously monitored and will be displayed and will be stored in the microcontroller.
A GSM handset is interfaced to the micro controller through DTMF encoder and decoder for sending the data and taking the command from the receiver.
At the receiver end micro controller interfaced with a GSM handset, DTMF decoder and an LCD display. For collecting the data the receiver GSM has to dial the number of transmitting GSM. As soon as the transmitting GSM receives the call it switches to sending mode. By pressing a pre defined number specifying that send the data from receiving GSM the transmitter will send the digital meter data and that parameter will be displayed on LCD at the receiving GSM side the.
