AUTOMATIC ELECTRICITY BILL GENERATING SYSTEM USING EMBEDDED TECHNOLOGY

Abstract

Currently, due to increased population and development of industries, the demand for electrical energy is increased. To measure the energy consumption of electrical appliances in a building, a nonintrusive load monitoring (NILM) method is used, in which the energy meter is installed with only a main supply. This method will identify loads that are currently active and provide a detailed accounting of energy consumption of loads. The proposed automatic electricity bill generation system uses the NILM method to measure energy consumption and to periodically provide information about the number of electricity units consumed along with the bill amount. By knowing the consumption of their household appliances, consumers can save energy by controlling their use. Existing billing systems generate electricity bills door-to-door at the end of two months using manual calculation but do not provide periodic billing information. Hence, there can be reading errors, and no energy savings are guaranteed. To overcome these issues the proposed system is designed to provide continuous monitoring of power consumption using the ACS712 current sensor and the corresponding amount calculated by the Arduino board. This system allows users to know exact electricity units consumed and bill amount. Hence, the chance of bill tampering is avoided in the proposed system. Periodically, it alerts consumers through LEDs and GSM messages so that they can manage their power consumption and add support for money management.
