"It is a prepaid energy meter. We have to pay first to use the electricity. If balance is zero, then we can’t use the electricity. We can recharge our energy meter by two methods. It is not the real life feasible project. It is just to show the concept of pre-paid energy meter.
By the use of RF principle: - In this, we have a wireless keypad at electricity center. This is used to recharge our energy meter. It includes RF module, microcontroller, LCD and relay.
By the use of GSM principle: - In this, our GSM mobile is used to recharge the energy meter. It includes a microcontroller, DTMF, LCD and relay."
