Abstract:
RF based Automatic meter reading, or AMR, is the technology of automatically collecting data from energy meter and transferring that data to a central database for billing and/or analyzing. This means that billing can be based on actual consumption rather than on an estimate based on previous consumption, giving customers better control of their use of electric energy. The Transmitter is connected to the meter and it counts the pulses from it and displays it over the LED display. It also transmit the data over RF. The data’s are also stored in the EEPROM. At the receiver end the data is received by an receiver module and the microcontroller will display it over the LED display.
