what is the project?
The proposed programmable energy meter helps to read the amount of energy used and it generates a bill for the same.
How it works?
This system works with the help of an Atmega microcontroller. It works with the help of pulses given to the meter which will detect the amount of energy used and calculate the cost. The calculated cost will be displayed on the LCD screen. When energy gets consumed it will generate the necessary pulses. It is powered by a 12V transformer. The GSM mechanism Is used by the user to know about the amount of power consumed and the cost. Once a call is placed, the system gets initiated, the user can then set or start the system. Set option helps to set the unit cost shoe the start option will start the unit calculation and its cost. The system works with ON/OFF command received through SMS. This system allows the user to calculate the amount of energy used and its cost for specific number of days as well.
