Electronic meter reader & data base management system

The objective of this paper is to develop a system which can transmit the meter reading of local area electric meter to the nearest electric meter billing and controlling station. For this we interfaced analog electric meter with the digital circuitry to provide real-time billing & reading to the customers by using Liquid Crystal Display (LCD). There are basically two ends, one is user end and the other is server end. The meter can either be prepaid or postpaid, which is completely monitored and controlled by the server end of a specific area. Each user will be provided by a pin code to access the meter either for recharge the meter bill or to check the balance in case of prepaid meter. The key elements of this research are micro controller, global system for mobile communication (GSM) module, and analog meter with IR module. The whole system is revolving a round the GSM module and the micro controller, where GSM module is used for the wireless data transmission and controller controls the whole operation of the system.
