This document describes a project to develop an Arduino-based automatic phase selector and IoT metering system for real-time energy monitoring. The system uses a Bluetooth module to allow users to select from available power sources like the electric utility, solar, and inverter. A Wi-Fi module is used to generate a webpage displaying source in use and power consumption data collected from the energy meter. The microcontroller interfaces the Bluetooth and Wi-Fi modules to update the information. The system aims to make electricity usage more user-friendly by providing selection options and consumption insights.

Introduction
 Automatic Phase Selector : When an electric utility outage occurs, the
Transfer Switch will switch to the backup source.
 With priority based sources having top priority to R (electric utility) and second
and third to remaining available sources like solar and inverter.
 The Internet-of-Things Energy Meter (IEM) is a device fixed on top of the
regular household power meter that provides detailed information about the
electricity usage.
 Modern power meters have a LED blinking every time a watt-hour is used, the
IEM detects these flashes using a interrupt, counts them, then the data is stored
to the cloud
 Overall the project is aimed to make electricity user friendly with giving them
information regarding their usage of utilities and consumption in a cloud.

Problem Identification
 In the earlier system there was no provision of informing the user and supplier
about the live source and power consumption.
 Also there wasn’t any provision of selecting the available sources by the users
according to their need.
 This problem can be easily solved by installing device ( wifi module &
Bluetooth module) that can inform the user in this reg.
 Working in this direction, it would be revolutionary to install such a system that
can provide user the flexibility and providing the knowledge of point to point
power consumption.

Objectives
 Our main objective is to :
 Develop a Arduino based auto phase selector & IoT metering system for
the real time monitoring for making electricity usage more user friendly.
 To install a Bluetooth module that provide the user an option to opt for a
desirous available sources.
 To install an IoT based webpage to collect energy consumption data and
sources in use.
 And program it and interface it with the main system so as to make it better to
be used by users and electricity grid for getting updated with having knowledge
of load under usage.

Methodology
The main system can be divided into 3 blocks.
➢ First block (Bluetooth module) : the module provides the platform to select the
available sources to users.
➢ Second block(Wi-Fi module): which is responsible for generating the webpage
containing information regarding the source under use and consumption of
electric power.
➢ Third block(microcontroller): the inputs of both the above blocks are fed to the
microcontroller which update and communicate the
