Development and Implementation of Energy Consumer Metering System with the Integration of Smart Users’ Management Model

Abstract

An electrical meter with the integration of the Internet of Things (IoT) device measures and records the consumption of electrical energy in residential and commercial buildings. This allows for remote monitoring and management of the energy usage through an IoT platform. This IoT meters emerged due to the inability of the existing metering system to smartly integrate the IoT application into the metering market. With the emergence of IoT technology, microcontrollers and sensors are deployed for this model to avert the aforementioned challenges. The microcontroller is responsible for collecting and processing data from the meter, as well as communicating with the other components of the device. The communication module enables the meter to connect to the Internet and transmit data to the cloud, to be accessed and analyzed through an IoT platform. The voltage and current sensors give input current and voltage signal for the microcontroller for analogue to digital conversion (ADC) effect as programmed. The experimental results indicate that the meter is accurate in measuring energy consumption with a maximum relative error of -6.06% as observed in Case 3 with a rated power of 40W and absolute current of 0.02A. The negative value of the relative error suggest that the measured energy is slightly lower than the actual energy consumed. The developed meter prototype engendered smart energy measurement with modern IoT technologies, this enables remote monitoring and of energy usage.
