The aim of the project is to automate the billing of energy meter and water meter. In
this project the front end is User friendly and the employees can work on this software with minimum knowledge of Computers. Employees can read the meter by sitting in the Office.
In this project the micro controller & the GSM unit is interfaced with the Energy meter/water meter of each house. Every house has a separate number, which is given by the corresponding authority. The GSM unit is fixed in the energy meter/water meter. The amount of consumption is stored in memory authority as SMS. Using this software we can send the SMS through Modem to that particular number which is assigned by these authorities and wait for the response. On other end the modem will receive the data in the form of a command and informs the controller to do the readings. After the readings the controller will send data to the modem. Modem, in turn sends data to the other end. In the office the GSM unit will receive the data and calculate the amount on LCD display. The number assigned by the authorities is Unique. Using GSM we can get the response very fast due to which time is saved. RTC is used to get the time. Memory is used to store the amount of units the user consumed. After sending the Readings to the Main server the Microcontroller will resets the memory to get the fresh readings.
