Development of Pre-paid Energy Meter using Internet of Things

This paper presents an implementation of IoT to develop a pre-paid energy meter system using an IoT prototype for monitoring and controlling energy and power consumption. This system is used for the remote or on-site management of energy and power consumption. The system provides a user interface using Global System for Mobile Communications (GSM) so the user can pay the required price for the desired unit. The system provides a web user interface to monitor energy and power consumption, including the number of units and price. The ultimate goal is to promote a sense of optimization of power usage by letting the user pay before they have access to electricity. The system consists of an energy meter box that is connected to individual load connections. This energy meter box consists of a microcontroller on Arduino, a GSM module, a voltage sensor, and current sensor, and an LCD. The LCDs are the energy and power consumed, the price remaining, and the number of units consumed.
