Hi suneela, here is a project on PREPAID ENERGY METER with circuits and code..

A scheme of Electricity billing system called “PREPAID ENERGY METER WITH TARIFF INDICATOR” can facilitate in improved cash flow management in energy utilities and can reduces problem associated with billing consumer living in isolated area and reduces deployment of manpower for taking meter readings. Every consumer can buy a memory card (is nothing but an EEPROM IC) with a password stored inside it using a MC program. The memory card is available at various ranges (ie. Rs 50, Rs 100, Rs 200 etc…).In our project we have given the name for memory card as smart card. When the consumer insert a smart card into the card reader which is connected in “prepaid energy meter with tariff indicator”kit.Then the card reader will read the stored information and delete the information from the EEPROM IC(smart card) using the MC program. So that the smart card cannot be reused by others. Suppose if a consumer buy a card for Rs.50/- he / she can insert this amount through the card reader so that prepaid energy meter with tariff indicator kit will be activated. According to the power consumption the amount will be reduced. When the amount is over, the relay will automatically shutdown the whole system. In our project we also have a provision to give an alarm sound to consumer before the whole amount is reduced.

PREPAID ELECTRICITY BILLING SYSTEM USING GSM

The short message system (SMS) of a standard mobile phone can be used for much more than just exchanging cryptic message. This application finds a humble mobile working for controlling external equipments. The SMS service provides by the service providers are comparatively low cost. Hence the system is highly efficient and low-cost.

Mobile phones have become a widespread means of communication. It becomes a part of everyday life with ever more people enjoying the service and extra freedom they provide. It works on the basis of Global System for Mobile Communication (GSM). A subscriber from any systems can access telecommunication services by using a Subscriber Identify Module (SIM) card in a handset suitable for the network on the visited system The Short Message Service allows text messages to be sent and received to and from mobile telephones. The text can comprise words or numbers or an alphanumeric combination. Because Simple person - to - person messaging is such an important component of total SMS traffic volumes, anything that simplifies message generation as well as extended utility of the SMS being sent is an important enabler of Short Message Service.

We will connect hardware kit i.e. GSM modem and microcontroller to the energy meter. The main aim of this project is whenever u r recharging with some amount say example Rs.100/- by doing SMS to the MODEM, the bulb gets automatically ON until your recharge gets zero. After getting your balance zero your device gets automatically switched OFF and you will get a message from the MODEM that you have to recharge your mobile and the process takes place continuously.
