    PREPAID ELECTRICITY BILLING SYSTEM

    USING GSM

    Abstract

    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 animportant 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 automaticallyswitched OFF and you will get a message from the MODEM that you have to recharge

    your mobile and the process takes place continuously.
