This project includes GSM (Sim800c) module, which is connected to Arduino through UART interface. Energy Meter signal taped through optocoupler to Arduino digital IO pin. Energy Meter gives signal through LED while calculating wattage. In this project we are considering LED signal as unit. Energy Meter output load controlled through relay which is connected to Arduino through digital IO pin.
By default Arduino has some amount which is hard coded. When load ON power calculation starts and units will increase. For each unit one rupee amount will decrease. For every three units SMS will upload to mobile number through GSM (sim800c) module. If amount reach minimum then it will send notification SMS. User can recharge amount from mobile SMS.
