GSM Based Smart controlled Digital Energy Meter with RFID Chip

Abstract: In the present day scenario, the energy consumption awareness plays an important role as its demand is growing day by day. Huge differences in energy production and consumption urges the need to reduce the power wastage. The prepaid electricity system proposed in this paper aims at reducing the wastage of power due to its theft and control its usage on the consumer side. This increases the overall efficiency of the power system. The RFID card enables a consumer to utilize the energy for which he has paid. A microcontroller continuously checks if his balance is within the threshold limit and he is notified when his balance goes below the limits. Once it exceeds the threshold value, the supply is automatically cut off. The user can then recharge by making an online payment whenever necessary. The LCD continuously shows the units of energy consumed.
