ELECTRICITY BILLING SYSTEM USING GSM



Abstract
Due to the drastic changes in technology in the last decade, so many advancements were introduced in electricity departments. The present system is like, a person from electricity department has to go to each and every house to take the readings from the digital meter and present these details to the billing department and after all their processing, they generate a bill and another person comes and gives the electricity bill to us and finally we have pay the bill.

To eliminate this long process and to make the work easy and also make the system totally an automated one, we have designed this project. Since the meter that reads the number of consumed units is actually a digital meter, it contains a controlling unit in it. To this unit, a zeegbee modem will be interfaced.
The modem provides the communication interface. It transports device protocols transparently over the network through a serial interface. The Zigbee modem is a wireless modem that works with a Zigbee wireless network.
         This system containing the energy meter calculates the power consumed by the house and sends the total number of units consumed and the amount to be paid for the consumed units, for a month, to the control unit where  one GSM modem is connected to along with Zigbee. The units received from the meter are taken by the Zigbee receiver and from there using the GSM modem the number of units is sent to electricity department and also to the user. The user has to pay the bill within the due date. If the user did not pay the amount within the due date, the electricity department sends a predefined message to the system containing the energy meter. Thus, this system shuts down completely and the user cannot use the power from the energy meter until he clears the bill amount.
