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. This system will be monitoring the input in KWH and generated bill will send to the user mobile in the form of SMS through GSM. We can control any the devices through GSM. The energy meters are connected to the Arduino Nano through an optocoupler. The optocoupler sensor gives an interrupt each time the meter LED ashes to the programmed Arduino and Arduino will calculate the bill based on KWH readings and sending this bill to the predefine mobile number through GSM. Based ON the generated bill user will control the load through SMS using GSM. In this system, an Arduino Nano is interfaced with an energy metering, GSM and Relay. In this project we are connecting loads through relay and CT. Here relays work as switch to on/off the power supply which is connected to the loads according to the signal received by the microcontroller. The status of the project will display on LCD. The main controlling device of the project is Arduino which is programmed by Embedded C language.    

Objectives:

1. To monitor electrical energy consumption in kilowatt-hours (kWh).
2. To calculate the electricity bill automatically based on energy usage.
3. To send bill details to the user through GSM-based SMS.
4. To display energy consumption and bill information on an LCD.
5. To enable remote monitoring of electricity usage.
6. To control electrical loads through SMS commands using GSM.
7. To switch loads ON and OFF using relay modules.
8. To reduce energy wastage through continuous monitoring.
