PROGRAMMABLE ENERGY METER WITH BILL ESTIMATION

Abstract

The main aim of the Programmable energy meter project is to estimate energy consumed by load with the help of an Atmega 328 and calculate the cost. Energy meter gives pulses which will be counted and displayed on LCD. These pulses occur depending on energy consumed. GSM to send SMS on amount of energy consumed. 12V Transformer to give power supply to the system. The user needs to make call which will be received and displayed on LCD and stored. The system then comes to setup mode from where the user can switch to start or setting option, setting to set unit cost. Start to know the unit consumed and the cost. The system switches the loads ON/OFF Depending on user commands received through SMS. The system also includes a feature in which user can specify the number of days for which the user wants to retrieve the consumed and the estimated cost for the specified days.
