The project is designed for reading electrical energy consumed in units and in rupees to display on an LCD screen to the user. This data is also provided to the electrical department using GSM technology for billing purposes. Owing to high electricity cost these days it becomes necessary for the consumer to know as to how much electricity is consumed to control electricity bill within his budget. In this proposed system, the consumer will get his energy consumption data on real time basis on a LCD display. The same data is sent through GSM modem to the electricity department via SMS.
A microcontroller of 8051 family is interfaced to the energy meter to get the Watt Hour pulses. The microcontroller then processes these pulses according the program written in it, to calculate the units consumed and cost involved.
Further it gives command to the SIM loaded GSM modem for sending the data to the electricity department via SMS. Further this project can be enhanced by to control the electrical appliances remotely via SMS. Also, the electricity department can send the monthly bill amount over SMS to the receiving unit for consumer information.
