Wireless Energy Meter reading on hand-held device based on RF Transceiver

The purpose of this project is to remote monitoring and control of the Digital Energy Meter. This system enables the Electricity Department to read the meter readings regularly without the person visiting inside each house. This can be achieved by the use of Microcontroller unit that continuously monitors and records the Energy Meter readings in its permanent (non-volatile) memory location. This system also makes use of a RF
Transceiver for transmitting the readings of Energy Meter. RF Communication ranges in between 30 KHz to 300 GHz. RF communication works by creating electromagnetic waves at a source and being able to pick up those electromagnetic waves at a particular destination. These electromagnetic waves travel through the air at near the speed of light. The wavelength of an electromagnetic signal is inversely proportional to the frequency; the higher the frequency, the shorter the wavelength. RF transceiver has both transmitter and receiver section with it. The Microcontroller based system continuously records the readings and the live meter reading can be sent to the Hand held device. The receiver end comprises of RF Transceiver, which receives the data from the transmitter. The data received at the receiver end is fed to the microcontroller present at the receiving end. The microcontroller at the receiving end is provided with a LCD. The readings received is processed and displayed on the LCD. The Microcontroller is programmed using Embedded C language.
