Design and Implementation of Home Appliance Energy Monitoring Device

Abstract

This paper presents the implementation of an energy monitoring device using Arduino Nano microcontroller to measure the power consumed by any individual electrical appliance in residential homes. It is also designed with the capability of sending measured electrical power parameters through SMS to owners when a request is made. The electrical energy and power are calculated based on measurements taken by Allegro ACS712 Hall effect current sensor and measured voltage over a time period. A novel feature of this device is its ability to also determine the start-up current of inductive loads. The device come in handy for homeowners who want to monitor the energy consumption of some appliances to reduce associated electricity bills. In addition, it could also be used for an energy audit of residential homes.

The Predictive Study on Soweto Wind Turbine Results and Port-Elizabeth

“…Realizing, that the shift towards a low-carbon energy requirement involves capital spending in wind turbines built on precise high-tech tools on wind farms [3][4][5][6][7][8]. Moreover, generation of electricity with the usage of fossil fuels contributes in increasing of pollutions from CO2 and other greenhouse gases emissions which are harmful to negative impacts on the environment [9,10]. According to [11], utilizing renewable energy as an alternative energy source will help reduce environmental problems, essentially GHG emissions and air pollution.…”
