Implementation of an RF based wireless automated energy metering and billing system

There are certain electrical power losses which have been affecting the availability of electrical power in developing countries. The rate of non-technical losses in developing countries is quite high which ranges from electricity theft and non-payment of bills. Therefore, this paper is aimed at the design and implementation of a Radio Frequency (RF) based wireless automatic energy meter reading system. This system uses a digital energy meter consisting of current and voltage sensors, analog to digital converters, a microcontroller and a Liquid Crystal Display (LCD) unit. The Base Station Wireless interfaced device was able to perform the desired interfacing function between the energy meter and the base station. Bills and reports were generated by the PC software and the outputs were found to be accurate. This system does not only reduce the cost of labour but also increases meter reading accuracy
