TITLE: GSM based prepaid energy meter system
AIM:The project aims in designing a system which makes electric bill payment easier and also controlling of digital meter for electricity department becomes more easily using GSM technology. The GSM modem provides the communication mechanism between the user and the energy meter by means of SMS messages. This project also sends SMS alerts to the user incase of balance goes below some set limit.
Description:Microcontroller is interfaced with GSM modem. « GSM based Pre-paid energy meter » is a modern era automation system where we can save the power. Here the devices to be controlled are interfaced with a GSM modem unit, which is capable of receiving instructions in the form of Short message service and performs the necessary tasks. A dedicated GSM modem with SIM card is required for each energy meter. The bill amount is also displayed on the LCD screen. The authorities can switch OFF the power to user if he doesn’t pay the bill, through simple SMS.
An EEPROM is provided on the board to store the updated recharge units and energy meter pulse count. At every instant the count value and units values are stored in EEPROM so that the data will not be lost even in power failure cases. When 1 unit is decremented from EEPROM the system will give a beep sound. When the recharged units become zero on power consumption, the system shutdown all the loads connected to it by giving a continuous beep sound. And the load will be disconnected from the supply with the help of relay. Again user has to recharge.
