Implementation of Smart Energy Meter through Prepaid Transaction using IoT

In India, energy meters are electro-mechanical and postpaid. The main drawback of this approach is that a person must walk from street to street, reading each house's energy meter and giving out the charges. According to that reading, the bill was paid. Even when bills are paid on time, issues like an over-billing amount or a provider warning are common. To overcome this problem, we proposed an IoT-based prepaid power recharge unit that will integrate with ordinary household energy meters and be capable of counting down energy use and switching off the main supply once the energy usage countdown hits zero, and a data collecting system using IoT. The recharge info and energy usage from the recharge station are saved in a Data Acquisition server connected to the energy meters to control the main power supply and monitor power consumption in real-time.
