ABSTRACT: IOT Smart Energy meter using Arduino UNO Blynk App controlling and Monitoring
Energy crisis is one of the major problems that the world faces today. The energy crisis can be reduced to a certain extent by properly monitoring our energy consumption and avoiding energy wastage.
The energy meters are connected to the Arduino UNO through an optocoupler. The optocoupler sensor gives an interrupt each time the meter LED ashes to the programmed Arduino and Arduino process this data to the ESP8266 WI-FI module then WI-FI module sends this data to the blynk app. This system monitors the kWh readings into the blynk app and LCD display. This design eliminates the human involvement in electricity maintenance.
In this system, an Arduino is interfaced with an energy metering circuit, current sensing circuit, WI-FI communication and a contactor to make or break power line. In this project we are connecting loads through relay and CT. Whenever over load was detected by the system then the Arduino will send the blink notification to the user mobile then user disconnect the load by using blynk application. Here relay works as switch to on/off the power supply which is connected to the load. The main controlling device of the project is Arduino which is programmed by Embedded C language.

Objectives:
The best remedy for this is not the increase in energy production, but the effective use of
available energy. By properly monitoring our energy consumption and avoiding energy
wastage, energy crisis can be reduced to a certain extent.
Consumer can monitor their energy consumption, and disconnect the load into the blynk app
User can get the over load alerts into the blynk app through Wi-Fi.
Monitoring KWH values on LCD display.
To turn on and off the load using relay switch.
User can control the devices from anywhere in the world.
To achieve this task using Arduino UNO microcontroller.
