Real-Time Monitoring and Control of Consumed Power for Household Appliances using Arduino Uno through Bluetooth and Android Application

In this work, Arduino Uno and Bluetooth controlled real time power measurement and control of household electrical appliances, was proposed. An android application was also been used to display the amount of real-time consumed power of each appliance separately and also to make the user aware the total billing amount. Along with measurement of total power consumed, this system also keeps a record of the total consumed electrical power in every hour and creates the load curve, which was used to estimate optimal billing amount based on two part tariff. The main focus in this work was imposed on reducing maximum demand power consumed by user so that total billing amount can be reduced. After estimation of load curve, system generates a time span within which all the appliances with relatively high power consumption capacity, should be used so that the average load curve becomes almost horizontal thus reducing maximum demand. The whole work was implemented on one tungsten bulb of 60 watt, two compact fluorescent light, each of 25 watt, one table fan of 40 watt and a DC electric motor of 1.2 HP. The optimal power consumption was displayed in an Android mobile phone through HC-05 Bluetooth module.
