Remote Electricity Billing
[attachment=89]
Abstract
Remote electricity billing is a unique concept, in which the electricity board can collect the consumed unit s data from consumer on mobile phone using GSM network. Each consumer is provided with a unique energy meter, which is having a GSM modem, microcontroller unit and a display unit internally. A SIM card is required for communication. Whenever this system receives an SMS from electricity board, it calculates the number of units consumed and billing amount on slab rate, displays on LCD for user interface. This system also sends the same message to the electricity board for departmental information and database.
The unique feature of this system is, the electricity board can disconnect or reconnect the connection from remote place through the mobile phone. As this project works on GSM network, the system can be controlled from any part of the world.
This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
