Abstract
Now a day's power saving is one of our major concern and above all we should use our energy resources according to our needs we are trying to make this innovative project keeping in mind that electric power should be conserved and should not be used without any limit for this we have used an innovative idea which has been already used in mobile phones in this we are using a concept of recharging of our electricity meter first with a fixed amount. Means the amount should be paid first to the electricity department then you can use the electricity of that amount whom which you recharged your meter.
Once your energy meter is recharged you can now enjoy electricity at your home wherever the energy meter is used now the current and voltage consumption of your house is sensed with the help of the CT and PT then microcontroller calculate the power consumed per hour then according to kilowatt per hour the price of the units consumed is deducted from the net amount with which you have recharged your energy meter so now you are getting uninterrupted power supply until you have the balance in your energy meter when last 10 units are left in your energy meter the meter start giving warning to the user with the help of buzzer and when the balance is equivalent to zero the electricity of your home get disconnected automatically then you have to recharge your energy meter again so that the cycle goes on. .
