IoT-based electricity energy monitoring system at Universiti Teknikal Malaysia Melaka

Abstract

Electricity bill is one of the major operating expenses in most of the commercial buildings and industrial plants. Thus, the buildings’ energy management system is an essential element that should be utilized to optimize the energy usage and hence, contributes to carbon footprint reduction. To achieve this, one needs to first understand how the energy is being used in the buildings before any saving measures can be identified and proposed. Therefore, this paper presents the development of an Internet of Things (IoT) enabled device that can communicate with different digital energy meters through modbus protocol. The prototype has been successfully installed in three locations in the main campus of Universiti Teknikal Malaysia Melaka (UTeM). The proposed solution enables the campus-wide energy usage to be monitored and stored efficiently and economically as opposed to the capital-intensive SCADA system.

Sistem Pemantauan Konsumsi Energi Listrik Berbasis Web Sebagai Upaya Konservasi Energi

“…Sistem pemantauan energi listrik pada jaringan tiga fasa dapat dilakukan dengan menggunakan tiga buah PZEM-004T meskipun memiliki kekurangan dalam penentuan tegangan dan arus antar fasa. Hal ini akan jauh lebih sederhana apabila sistem pemantauan pada jaringan tiga fasa menggunakan power meter tiga fasa seperti PM 810 [11], [12]. Kelebihan dari penggunaan perangkat ini adalah, pada hampir keseluruhan power meter yang telah memenuhi standar mampu mengatasi semua permasalahan yang telah disampaikan.…”

IoT based monitoring of air quality and traffic using regression analysis

“…Nowadays, with the development of the so-called 'smart city', new sensor-based alternatives are appearing. The 'smart city' is a name given to a city that incorporates information and communication technologies (ICTs) in order to improve the efficiency and reliability of city services like electricity [31,32], mobility [33], and other services [34][35][36]. One of the major problems related to the IoT in the smart city is the integration and interconnection of lots of IoT objects, such as sensors, actuators, etc.…”

Design and implementation of internet of things-based electrical monitoring system

“…In study presented by [10], the Nodemcu microcontroller, which gives the ability to connect to Wi-Fi continually and fetch data for sensors in real time, was used, and the system was monitored and controlled using the blynk program for the mobile phone. The study in [11] explains how to use WSN to create a lowcost farm management system that can detect soil moisture as well as the environment, as well as weather and prediction to future agricultural activities.…”
