Abstract: This paper presents a single phase digital energy meter based on a microcontroller. This digital meter does not have any rotating parts, and the energy consumption can be easily read from a digital display also at remote place it is easily possible to check energy consumption and tampering detection by using GSM technology. When supply wills cut-off, the meter will restart with the stored value. Today energy theft is a worldwide problem that contributes heavily to revenue losses. Consumers have been found manipulating their electric meters; try to make them stop, or even bypassing the meter, effectively using power without paying for it. This energy meter can detect tampering in an energy meter by using microcontroller and provide there details at remote location.

Keywords: Tampering Detection, GSM Technology, microcontroller, RMR (Remote Meter Reading).
