As a consumer, you must add a certain amount of money to your prepaid card. It can then be fed into the microcontroller as an input. The microcontroller collects information from electricity meters and prepaid cards. Then, it compares the energy meter reading with the energy limit value to display the amount of energy consumed on the LCD or LED display. Prepaid energy meters display energy consumption in the form of 1 unit or 1 kWh. 1 kWh refers to the unit of energy required to provide 1000 watts of power in 1 hour.
The prepaid electricity meter is programmed so that once the funds are used up, the power supply will stop. When you recharge the prepaid card, the balance will increase and the relay (automatic switch) allows the power to be turned on again. You will receive notifications about daily energy consumption and existing balance via SMS or email. This will help you understand when the prepaid card is recharged before the balance reaches zero. The display of the prepaid electricity meter also shows your energy consumption and balance.
