description

In this project we show that how we interface the digital energy meter to the easy recharge unit and convert this meter into prepaid energy meter. By using this technique we show that how we convert all meter with the prepaid logic. B y using this type of technology it is possible to stop he misuse of electricity. Normally in every postpaid connection bill is much higher then the prepaid. When there is postpaid, no body want to take care of the wastage, but at the end of month when bill is present then bill is paid by the house inch rage, small workers in the office, employees in the school, in all the private and Govt office no body want to take care of the wastage. So we add some innovative idea to avoid and save this valuable energy for everyone.

In this project we will interface digital energy meter to the easy recharge unit and hence convert it into a prepaid energy meter

By using this technology, we will be able to minimize the losses occurred by corrupt employees

This also takes care of the excessive wastage of energy

The LCD screen(2 lines and 16 characters) is used for displaying the balanced amount and the units consumed.

The microcontroller AT89C51(40 pin, 128 byte RAM, 4K byte ROM), is used for controlling LCD display, start and stop functions, checking of balance and control the load as per balance.

The IC 8870, is used to provide GSM interface.The IC 74154, a BCD to decimal decoder, is attached

with microcontroller to interface with a dtmf decoder5V regulated voltage supply is used to provide

regulated voltage to the microcontroller
