Abstract -Saving energy is high on the agenda for consumers and businesses, but with most of the electrical devices today, it‘s difficult to know how much energy we are actually using at any given point in time. Smart Energy Meter is a meter which helps the consumers to know their day to day power consumption to better control their usage and producers to manage production. This meter records consumption of electric energy in intervals of hour or less. Smart meters enable two-way communication between the meter and the central system. The proposed project comprises of hardware design using a low-cost 8-bit P89C51RD2xx microcontroller and the complete hardware design will be proposed .The Communication is through SMS. They are two one is admin password and second is user. By this admin password the cost per unit can be changed by the concerned officer. The system software driver is also developed using embedded-C programming language in Keil µVision 4 IDE. Smart meters are also believed to be a less costly alternative to traditional interval or time-of-use meters and are intended to be used on a wide scale with all customer classes, including residential customers. The project also addresses about the various debugging tools such as Keil µVision 4 C51 debugger and Flash magic tool 9.25 version used to test the implemented prototype.
