POWER MONITORING SYSTEM USING MICROCONTROLLER FOR OPTIMUM POWER UTILITY IN HOMES

Abstract

This project explains the design and implementation of an electronic system based on development of an automated household utility power monitoring system using Arduino. It utilizes the Arduino Nano board intended for use in conjunction with the ATmega328 chip. A current transformer through the sensor circuit is connected for monitoring the power. The system has been designed and used to monitor electrical parameters such as voltage, current and power of household appliances. The system consists of a smart sensing unit that detects and controls the home electrical appliances used for daily activities by following different tariff rates. Results are shown on Nokia Display 5110 which intends that the current transformer is working properly. As the supply and demand of electrical energy is challenged within the context of environmental awareness and which is evaluated by household monitoring. It can reduce costs for the consumers and thereby improve grid stability. A developed prototype has been extensively tested and experimental results have compared with conventional measuring devices.
